PCT No. PCT/FR89/00520 Sec. 371 Date Apr. 11, 1991 Sec. 102(e) Date Apr. 11, 1991 PCT Filed Oct. 10, 1989 PCT Pub. No. WO90/03972 PCT Pub. Date Apr. 19, 1990.The present invention relates to novel 4-methyl-5-[2-(4-phenylpiperazin-1-yl)ethyl]thiazole derivatives of the general formula <IMAGE> (I) in which R is selected from a hydrogen atom, an alkyl radical having from 2 to 7 carbon atoms and an aralkyl radical of which the aryl moiety preferably consists of phenyl and of which the alkyl moiety has from 1 to 4 carbon atoms, and to the pharmaceutically acceptable salts of these derivatives. It further relates to a method of preparing these products and to pharmaceutical compositions in which they are incorporated.
