실험 절차

The title compound was prepared by the procedure of Example 10 using N-(4-bromobutyl)-N'-(4-carbomethoxythien-3-yl)urea (6.92 g, 21 mmol) and 4-(4-fluorobenzoyl)piperidine hydrochloride (10.16 g, 42 mmol). The urea was prepared by reacting methyl 4-aminothiophene-3-carboxylate with 4-bromobutylisocyanate in toluene at room temperature for 12 hours to produce the urea as a tan solid, mp 85°-86° C. There was obtained 3.62 g (40.8% yield) of the title compound as a brown solid. This material was recrystallized from CH2Cl2 /ether, mp 190°-192° C.
