Benzophenone derivatives and process for their production
Abstract
Abstract The present invention relates to pharmacologically valuable new benzophenone derivatives having a pronounced sedative action on the central nervous system and some of which also possess muscle-relaxing and aggression-inhibiting properties. These new derivatives have the structural formula ##EQU1## and their acid addition salts, in which R 1 and R 2 are substituents selected from the group consisting of hydrogen, saturated and unsaturated alkyl groups having 1-4 carbon atoms; R 3 is a substituent selected from the group consisting of --CN, --CONH 2 , --COOCH 3 , --COOC 2 H 5 , --COOH, and --COOMe, where Me is a metallic cation; n is an integer selected from 1 and 2; and m is an integer selected from 1,2, and 3, and wherein the rings A and B may be substituted, ring A being substituted preferably with a halogen such as chlorine or with nitro, trifluoromethyl, methyl, methoxy or methylmercapto, preferably in the 5 position, and ring B being preferably substituted in the 2' position with chlorine or fluorine. The radicals R 1 and R 2 preferably signify hydrogen or a methyl group, or a n-butyl group in the case of Ring B.
