Procedure

4-Isopropylbenzyl chloride (0.84 g, 0.005 m), 4-benzoylureidopiperidine (1.28 g, 0.005 m) and triethylamine (0.6 g) in dimethylformamide (25 cm3) were stirred at room temperature for 24 hours. Water was added and the precipitated solid filtered off. The solid was suspended in isopropylalcohol and acidified with ethanolic HCl. The title compound was filtered off and dried (1.2 g), m.p. 240°-242° C. as the hydrochloride salt, hemihydrate.
