Title compds. (I)[R1=acylamino, N-acyl-N-(lower) alkylamino; R2=H, lower alkyl, aryl; R3=H, NO2, amino, OH, lower alkoxy; A=lower alkylene; Q=H, halo were prepd. Thus, 2.18ml cyclopropylcarbonyl chloride in 2.5ml methylene chloride was reacted with a mixt. contg. 3.0g 4-[4-(3-indollyl)piperidinomethyl -2-aminothiazole, 5.4ml triethylamine, and 30ml N,N-dimethylformamide to give 2.9g 4-[4-(3- indollyl)-piperidinomethyl -2-cyclopropyl carbonylaminothiazole.
