Abstract

The invention comprises compounds of the general formula <FORM:0985657/C2/1> wherein R1, R2 and R3 each represents a halogen atom or an alkyl, alkoxy alkylthio,nitro,trifluoromethyl, carboxy, alkoxycarbonyl, carbamyl or cyano group, but at least one of which is a carboxy, alkoxycarbonyl, carbamyl or cyano group and wherein the broken lines denote that the groups attached thereby are optional, and acid addition salts thereof and a process for the preparation thereof by reacting a benzophenone of the general formula <FORM:0985657/C2/2> with an a -amino acid or an ester thereof of the general formula <FORM:0985657/C2/3> or by reacting said benzophenone with a halogeno-acyl halide of the general formula <FORM:0985657/C2/4> and treating the (halogenoacyl-amido)-benzophenone obtained with ammonia and, in either case where required, transforming the reaction product into an acid addition salt. Pharmaceutical preparations containing the above compounds and having sedative, tranquillizing, muscle relaxing, and anticonvulsant activity are administered enterally or parenterally, e.g. as tablets, dragees, suppositories, capsules, solutions, emulsions or suspensions. Specifications 985,658 is referred to.
