To a solution of 0.29 mmol (4-hydroxy-piperidin-1-yl)-(2-isopropoxy-5-methanesulfonyl-phenyl)-methanone in 6 ml dichloromethane at 0° C. were added successively 0.73 mmol triethylamine and 0.35 mmol methanesulfonyl chloride. The reaction mixture was stirred at 0° C. for 20 min and then at RT for 2 h. The reaction mixture was then diluted with dichloromethane, washed with water, and the organic phase dried over sodium sulfate and concentrated in vacuo to afford the title compound as a light brown solid (yield 93%). MS (m/e): 420.1 (M+H+, 100%).
