Reaktionsschritte
The 1-(4-methylaminobenzoyl)-4-[2-(4-methylmercaptophenyl)ethyl]piperazine is prepared from 1.66 g of 4-methylaminobenzoic acid, 1.95 g of N,N-carbonyldiimidazole and 2.35 g of 1-[2-(4-methylmercaptophenyl)ethyl]piperazine in dimethylformamide at 85°. The base is purified via the hydrochloride (m.p. 185°, decomp.) and melts at 120°-121°.
