Procedure

To a solution of 1-(benzyloxycarbonyl)-4-[[2-(3,4,5-trimethoxyphenyl)pyridin-4-yl]methyloxy]piperidine (213 mg) in methanol (10 mL) was added 40% aqueous potassium hydroxide (10 mL). The mixture was stirred at 100° C. for 3 hours and evaporated. Water was added to the residue and extracted with chloroform. The organic layer was washed with brine, dried over anhydrous sodium sulfate and evaporated. The residual oil was subjected to column chromatography of silica gel using chloroform-ammonia saturated methanol (20:1) to give the title compound.
