Abstract

1444529 Benzodiazepines F HOFFMANNLA ROCHE & CO AG 27 June 1975 [28 June 1974] 27279/75 Heading C2C 3S-Compounds of the general Formula (I) (R 1 =H, C 1-5 alkyl; R 2 = halogen) are prepared by (a) cyclizing a compound of the Formula (II) or (b) reacting a compound of the Formula (III) with L-alanine or a reactive derivative thereof, optionally followed by alkylation. The preparation of starting materials of Formula (II) and (-)-benzyl 1-[2-(o-chlorobenzoyl)- 4-nitrophenylcarbamoyl]ethylcarbamate is described. The above compounds are anthelmintics, muscle relaxants, anticonvulsants and sedatives, and may be administered in the form of pharmaceutical preparations containing them in association with a carrier.
