    Abstract: 1314118 2 - Aminonaphthaquinone derivatives F HOFFMANN-LA ROCHE & CO AG 16 July 1971 [17 July 1970] 33475/71 Heading C2C Novel compounds of Formula I: wherein R is H, halogen or C 1-4 alkoxy and R 1 is a group of Formula Ib: or Ia: wherein R 2 is H, C 1-7 alkyl, phenyl optionally substituted by halogen, nitro, amino or hydroxy or is phenyl-(C 1-4 )-alkyl or a salt thereof, are prepared either by oxidation of a compound of Formula IV: or by reaction of a compound of Formula II: wherein R 3 is acyloxy, alkoxy, aryloxy, aralkoxy, arylthio, aralkylthio, hydroxy or halogen with an amine R 1 -NH 2 , and optionally converting a compound wherein R is H or halogen other than chlorine into a compound where R is chlorine or any compound into an acid addition salt. 2 - (2 - Endo - bornylamino) - 3 - chloro - 1,4- dihydroxy-naphthalene is prepared by reduction of the corresponding naphthaquinone. Amines of formula R 1 -NH 2 are prepared either by reduction of the corresponding oxime R 1 =NOH optionally with separation of stereoisomers by crystallization of the acetates or by hydrolysis of the N-acetylamino compound and where R 2 is nitro-phenyl, by nitration of the compound where R 2 is phenyl prior to hydrolysis. The N-acetyl compounds R 1 -NACOCH 3 are prepared by reaction of the appropriate 2-R 2 -2-borneol with acetonitrile. 2-Heptyl-2-borneol is prepared by reduction of 2-heptynyl-2-borneol obtained by reaction of camphor 1-heptyne and ethylmagnesium bromide. N - (4 - Phenethyl - 2 - exobornyl) - acetamide is obtained by reaction of acetonitrile with 2-(1- phenethylidene)-camphane obtained by reaction of 2-phenethylborneol with acetic anhydride. Pharmaceutical compositions in conventional forms for oral, rectal or parenteral administration and having amoebicidal and bacteriostatic activity comprise an above novel compound and a carrier therefor.
