Reaction Steps

To a stirred mixture of 7.7 g of 1-(4-chlorophenyl)-6-(4-methylthiophenyl)-2-piperidone, 80 ml of methylene chloride, 3 g of silica gel, and 2.2 g of water was added 3.44 g of sulfuryl chloride at 15° to 25° C., and the mixture was stirred at 15° to 25° C. for 2 hours. The reaction mixture was poured into a cold aqueous sodium hydrogen carbonate solution. The methylene chloride solution was washed with a saturated aqueous sodium chloride solution, dried, and concentrated. The residue was purified by silica gel column chromatography (solvent; ethyl acetate:ethanol=10:1) and recrystallization from ethyl acetate to give 7.69 g of 1-(4-chlorophenyl)-6-(4-methylsulfinylphenyl)-2-piperidone as colorless prisms.
