Procedure

To an ice-cooled solution of 27.6 g (107 mmol) of trans-[4-(tert-butyl-dimethyl-silanyloxymethyl)-cyclohexyl]-methanol and 9.99 ml (128 mmol) of methanesulfonyl chloride in 350 ml of dichloromethane was added under stirring at 0–10° C. 29.6 ml (213 mmol) of triethylamine within 20 minutes. The reaction-mixture was stirred for 1 hour at room temperature. It was then partitioned between dichloromethane, 1N HCl and water. The dichloromethane-phase was dried over magnesium sulfate and concentrated to yield 38.2 g crude trans-methanesulfonic acid 4-(tert-butyl-dimethyl-silanyloxymethyl)-cyclohexylmethyl ester as colorless viscous oil, MS: 354 (M+NH4+).
