Procedure

As for the preparation described in Example 39, 1.6 ml (11.4 mmol) of triethylamine and 0.74 ml (9.55 mmol) of methanesulfonylchloride in 15 ml of dry dichloromethane are added to 1.3 g (7.6 mmol) of (E)-3-(t-butyldimethylsilyl)-2-propen-1-ol. [Lipshutz et al., J. Org. Chem. 54(21), 4975 (1989)] in 20 ml of dry dichloromethane to give after purification by flash chromatography on silica gel and elution with petroleum ether: ethyl acetate 9:1 1.3 g (67%) of expected (E)-3-(t-butyldimethylsilyl)-2-propen-1-ol, methanesulfonate as a colorless liquid.
