Procedure
A solution of triethylamine (2.5 eq) and 4-methoxy-2,6-dimethylbenzenesulfonyl chloride (13.04 mmol, 1 eq) in MC (10 ml) was added dropwise to a solution of piperidin-2-ylmethanol (13.04 mmol) in MC (30 ml) at 0° C. and the mixture was stirred at 0° C. for 30 min. It was then stirred at room temperature for 14 h, MC (50 ml) was subsequently added to the mixture and the mixture was washed with water and sat. sodium chloride solution. The organic phase was dried (Na2SO4) and concentrated in vacuo. The crude product obtained in this way was purified by column chromatography. Yield: 3.2 g (79%)
