  • Patent number: 4189495
    Abstract: The invention provides novel 2-methoxy-benzamide derivatives of the formula: ##STR1## in which n is 1 or 2; R.sub.1 represents a cycloalkyl-alkyl radical of formula: ##STR2## a phenylalkyl radical of formula ##STR3## (in which m is an integer from 2 to 5, A is a linear or branched alkylene chain of 1 to 4 carbon atoms, and R.sub.4 is hydrogen, halogen, especially fluorine or chlorine, trifluoromethyl, or alkyl or alkoxy of 1 to 3 carbon atoms), CNCH.sub.2 --CH.sub.2 --, CH.tbd.C--CH.sub.2 --, ##STR4## R.sub.2 is either chlorine, SO.sub.2 R.sub.5 (in which R.sub.5 is alkyl of 1 to 4 carbon atoms), or SO.sub.2 NR.sub.6 R.sub.7 (in which, R.sub.6 and R.sub.7, which are identical or different, represent, independently of one another, hydrogen or alkyl of 1 to 4 carbon atoms); and R.sub.3 is hydrogen or alkyl of 1 to 4 carbon atoms; in the form of racemates or optical isomers, and their pharmaceutically acceptable acid addition salts, which are useful in the treatment of psychosomatic and pyschotic disturbances.
