Versuchsvorschrift

A solution of 0.51 g (2.99 mmol) of 2,2-dimethyl-3-piperidin-1-yl-propan-1-ol in 7 ml of dichloromethane was treated at 0° C. with 0.24 ml (179.59 mmol) of methanesulfonyl chloride and stirred at RT for 2.5 h. The reaction was extracted with aqueous saturated NaHCO3 /Et2O (3×). The organic phases were washed with aqueous saturated NaHCO3, dried over Na2SO4 and evaporated to give 0.85 g (quantitative) of the title compound as light brown oil. MS: 249.2 (M+).
