Reaction Steps

A 270 mg portion of 4-[2,5-dimethyl-4-(thiomorpholine-4-carbonyl)piperazin-1-yl]-2-trifluoromethylbenzonitrile synthesized in Example 7-6 was dissolved in 7 ml of dichloromethane, and the solution was mixed with 110 mg of sodium bicarbonate and 155 mg of m-chloroperbenzoic acid (MCPBA) at −78° C. and stirred at the same temperature for 6 hours. The reaction solution was mixed with chloroform, washed with 1 N aqueous sodium hydroxide and saturated brine and then dried over sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by a silica gel column chromatography to obtain 232 mg of the title compound from methanol-chloroform (1:50, v/v) eluate.
