The fir~t of the foregoing two reactions i~ generally cond~cted in an inert organic ~olvent, generally a polar 801-vent such ~s an alcohol, as for e~Emple me~hanol, ethanol or isopropano~, a k~tone such as ace~one or methyle~hyl ketone9 an alkanoic acid such as acetic acid~ an e~her such as ethyl ether and tetrah~drofuran.

An alkylmercaptan is formed as a by-product and the desired product is ob~ained by cooling the reaction mixture and collectlng the solid whlch can be purified if desired by conventional technlques such as recrys-~allization.

Many of the ~hioureas used a~ s~arting ma~erials in the first reaction are known (see Olin and Dains~ J.Amer.
Chem. 5OC. 521 3326 (1930) and U.S. Patent No. 2,593,502) while others can easily be ob~ained by known processes. The thioureas are generally prepared from known N-acylthioureas lsee, e.g. t'Berichte der deutschen Chemischen Gesellschaft", S, 755 (1873); Ann, Chim. (5) 11, 313 ~1877); J. Amer. Chem.
Soc~ 62, 3274 (1940)], which are reac~ed with alkylating agents ~uch as alkyl halides, alkyl sulphates or alkyl sulphona~es to give the corresponding S-alkyl-N-acyl-isothioureas [see9 e.g. J. Org. Chem. 30, 560~ (1965~; Ch~m. Pharm. Bull. (To~yo), 9~ 245, ~1961)]. These S-alkyl-N-aoyl-iso~hioureas are then reacted with halogenoformic acid esters or with pyrocarbonic acid dialkyl esters lsee,e.g. Ber. dtsch, c~em~ Ges. 71, 1797 (1933)] ~o give the ~-~lkyl-N-acyl-N'-alkoxye~rbonyl-isothio-ureas7 which corresponds to ~he known subs~itution of S-alkyl-iso~hioureas with chloroformic acid alkyl esters [see, e.g.
J. Amer. Ghem. Soc. 52, 3326 (1930)~
The ~ollowlng are typical isothioureas whioh can 2Q be employed in accordance with the process o~ this invention:
~,NJ-bis-methoxycarbonyl-5-methyl-isothiourea (melting point 99 - 100C), N,~'-bis-ethoxycarbonyl-S-me~hyl-isothiourea (melting point 50 - 51C), N-ethoxycarbo~yl-~'-propionyl~S-methyl-isothiourea (melting point 92 - 94C~, N-methoxy-carbon~l-N'-propionyl-S-methyl-i~othiourea (melt~ng poin~
97 ~ 99C~, N-metho~yoarbonyl N'-ethoxy~cetyl-S-methyl-iso-thiourea (meltin~ point 6~ - 70C), N-metho~ycarbonyl-MI-_ ~ _ cyclohexylcarbonyl-S-methyl-iso~hiourea (m.p. 67 - 68C), N-methoxycarbonyl-N 7 -phenylacetyl-S-me~hyl-isothiourea (m.p.
55 - 56C~, N-ethoxycarbonyl-N'-benzoyl-S-methyl-isothiourea (m.p. 79 - 80C) 3 N-etho~ycarbonyl-N'-methoxycarbonyl-S-methyl-isothiourea (m.p. 69C)? N-allyloxycarbonyl-N'-metho~ycarbonyl-S-methyl-isothiourea, N-propinyloxycarbonyl-N'-methoxycarbonyl-S-methyl-isothiourea, N,N'-bis-allyloxycarbonyl-S-methyl-iso~
thiourea and N,NI-bis-propinylo~ycarbonyl-S-methyl-isothiourea.
Mo~t of the 2-aminoanilide starting materials are know~. Those that are not previously known can be readily pre-pared by methods analogous to those disclosed in the llterature.
For example, a 2-nitroaniline having the appropriate substi-tuent in the 4- or 5-position, e.g.~ pheno~y, phenylthio, phenyl-sulfinyl or phenylsulfonyl, can be N-acylated with an acid chloride of the formula R4COCl to yield the correspond~ng 2-nitro~4- or 5-substituted anilide which ~s hydrogenated as with Raney nickel to y~eld the 2-2mino-4- or 5-subætitu~ed anilide.
The 2-nitroanilines having a phenylsulfinyl or phenylsulfonyl group in th~ 4- or 5-position~ can also be ob~ained from the . 20 corresponding phenylthio compounds through controlled oa~ida~io analogous to that described above~ e.g. using hydrogen peroxide ln acetic anhydride or perbenzoic acid in dioxane or chlorofo~m, to yield the sulfinyl compound, or ~rdrogen peroxide in glacial acetic acid to yield the sulfo~e. The 4 and 5-phenylsulfonyl-2-nitroanilines c~n al~o be obtained by the reaction of a ~od~umbenzenesulfinat~3 with a 4- or 5-chloro-2-nitroaniline a3 for example dimethylformamide at about 140C.

The effectiveness is determined by quantitatively coun~-ing the worm eggs~ excreted with the faeces~ before and after the treatment.

Complete cessation of the excretion of eggs after the treatment denotes that the worms have been expelled or have been so damaged ~hat they can no longer produce any eggs (effective dose).
The active eompounds tested and the effective dosages (minimum effective dose~ can be seen from Table 3.

The compounds of the inventlon are employed to com-bat helmintic infestations, both prophylactically and thera-peutically, in humans and other animals through administration thereto of an anthelmintically effective amoun~ of one or more compounds. Generally such an amoun~ will range from about 0.1 mg/kg to about 50 mg/kg of body weight~ dependlng upon the stage and severity of the infestation. This range is of course merely a guideline and the ac~ual dose should be ti~rated to the recipien~ keeping in mind his age, general health and body weight, the response to treatment and the type of formula~ion. At times less than 0.1 mg/kg will suffice while at others more than 50 mg/kg can be indicated. The total d~lly dose t~us will generally be from about 5 mg o .
about 5 g~ although here again ~his is merely a guideline~
The compounds of the present invention are administered parenterally or orally in any of t~e usual pharmaceutical oL~s.
The~e lnclude solid and liquld oral unit dosage forms such as ~tablets, capsules, powders 9 suspensions~ solutions, syrups and the like, including sus~ained release prepara~ions, and fluid ln~ectable form~ such as sterile sol~tions.and suspensions.
Th~ term unit dosage form as used in this specification and the claims refer to physically discrete units to be ~dministered in ~ngle or mul~iple dosage to animals9 each uni~ con~aining a pr~determined quant~ty of active material in association with ~h~ required diluent, carrier or veh~cle. The qu~ntity of astlve material is that c~lculated to produce the desired ~hera-peutic effect upon administration of one or more of ~uch unit : . . . .
. . . , ~ , r7 ~

Powders ~re prepared ~y comm~ nuting the compound to a ~u~cable fine size and mixing with a similarly coTmrinuted diluent pharmaceut:ical carrier such ~s an edible carbohydrate material as for example, starch. Swee~ening, flavoring, pre~ervative, dispersing and coloring agents can also be present~
Capsules are made by preparing a powder mix~ure as de~cribed above and filling ~ormed gelatin shea~hs. A lubricant such as talc, magnesium stearate and calcium st arate can be added to th~ powder mixture as an adjuvant before the filling io operatlcn; a glldant such as colloidal silica may be added to improve flow pr~perties; a disintegra~ing or solubilizing agent ~ay be added to improve the availability of he medicament when ~he capsule is inges~ed.

Tablets are made by preparing a powder mixture~
granulating or slugging, adding a lubricant and disintegrant and pressing into tablets. A powder mix~ure is prepared by mdxing the compoundj suitably comminutedg wi~h a diluent or base such as starch, sucrose, kaolin, dicalcium phosphate and the like. The powder mixture can be granulated Sy wetting 20 wlth a binder such as syrup, starch paste, acacia mucilage or ~olutions of cellulosic or polymeric materials and forcing thrl~ugh a ~creenO As an alternative to granula~cing, the powder ~xture can be run through the tablet machLne and the resulting ~perect~y formed 81ugs broken into granule~. The granules c~n be lubricated to prevcnt ~ticking to the table~ forming die8 by means o~ the addition of ~tearlc acid, a stear~te sal~g . .

talc or m$neral oil9 The lubricated mixture is then compres~ed into tablets. The medicaments can also be combined with free flowing inert carriers and compressed in~o table~s directly wlthout going through the granulating or slugging stepsO A
protectlve coati~g eonsisting of a ~esling coat of shellac, a coating of sugar or polymeric ~aterial and a polish coating o wax san be provided~ Dyestuffs can be added to these coatings : to distinguish differen~ uni~ dosage~.

Oral fluids such as syrups and elixirs can be prepared in unit d~sage form so that a given quanti~y9 e.g.~ a teaspoon-ful, contains a predetermined amount of ~he compound. Syrups ~an be prepared by dissolving the compound in a sultably flavored aqueous sucrose sol~tion while elixirs are prepared throu~h the u~e of a non~toxic alcoholic vehicle. Su~pensions can be formu-lated by dispersing the compound in a non-tox~c vehicle in whic~
it is insoluble.

~ luid unit dosage forms for parenteral administration ~an be prepared by suspending or dlssolving a measured a~ount of the compound in a non~toxic liquid vehicle suitable for ~n~ection such as an aqueous or oleaginous ~edium ~nd s~eriliz-~ng the suspension or solution. Alternativ~ly a measured amount of the eompound ls placed ln a vial and the vial and i~s con-~ ten~s a~e sterilized and sealed~ Rn accompanying vial or - ~ehicle can be provided o~ mixing prior to adminis~ration.
