実験手順

2-(2-Methoxyphenoxy)ethyl bromide (2.31 g.), 4-benzamidopiperidine (2.04 g.) and anhydrous potassium carbonate (1.38 g.) were well mixed and heated on a steam bath for 4 hr. The resultng mass was crushed and stirred in water (200 ml.) at 60° for 12 hr. Filtration afforded the crude base of the title compound (2.95 g.). Conversion to the hydrochloride by solution in ethanol/HCl and precipitation with ether provided 3.01 g. of the title compound, as the hydrochloride m.p. 193.4° .
