実験手順

3-{2-[4-(4-Methoxyphenyl)-1-piperazinyl]ethyl-2-trifluoroacetylimino-6-trifluoromethoxybenzothiazoline hydrochloride may be prepared in the following manner: a mixture of 2-(2-trifluoroacetylimino-6-trifluoromethoxy-3-benzothiazolinyl)ethyl methanesulphonate (4.52 g), toluene (120 cc) and the base liberated from 4-(p-methoxyphenyl)piperazine dihydrochloride (10.56 g) is heated to reflux for 1 hour, cooled to +4° C. and then drained. The toluene filtrate is evaporated under reduced pressure and then treated with 1.2N aqueous hydrochloric acid solution (45 cc). The hydrochloride separates in amorphous form and then crystallizes on grinding with ethanol (50 cc). After draining, washing with ethanol (15 cc) and drying at 50° C. at 20 mmHg, 3-{2-[4-(4-methoxyphenyl)-1-piperazinyl]ethyl}-2-trifluoroacetylimino-6-trifluoromethoxybenzothiazoline hydrochloride (1.7 g) is obtained.
