Reaction Steps

A mixture of 4-benzyloxy-N-(3-chloro-propyl)-benzamide (0.5 g, 1.64 mmol), ), 4-benzyl-4-hydroxy-piperidine (0.315 g, 1.65 mmol), potassium carbonate (0.45 g, 3.29 mmol) and 2-butanone (10 ml) was stirred at 60° C. for 48 h. After the addition of water, the mixture was extracted with ethyl acetate. The organic layer was dried (Na2SO4), filtered and evaporated. The residue was purified by chromatography (silica gel, methylene chloride-methanol from 95:5 to 9:1) to give N-[3-(4-benzyl-4-hydroxy-piperidin-1-yl)-propyl]-4-benzyloxy-benzamide (185 mg, 25%) as a light yellow solid. MS: me/e=459 (M+H)+.
