Reaction Steps

To a solution the product of step 2 (1.1 g) in DMF (15 ml) were added 4-(4-chlorophenyl)-4-hydroxypiperidine (0.81 g) and potassium carbonate (0.53 g) and the mixture was stirred at room temperature for 3 hours. Water and ethyl acetate were added to the reaction mixture, the organic layer was separated and washed with saturated aqueous sodium chloride, and dried with magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography eluting with methylene chloride-methanol (10:1) to give the titled compound as major regioisomer (0.86 g) and minor one (0.05 g). Major isomer
