Procedure

To 6-t-butyldimethylsilyloxymethyl-4-hydroxytetrahydropyran-2-one (0.50 parts) in dichloromethane (10 parts) at ambient temperature was added pyridine (0.20 parts) followed by a solution of acetylchloride (0.20 parts) in dichloromethane (2 parts). After 1 hour at 20°-25° C. less than 2% starting material remained by GLC analysis. The reaction mixture was then washed with water, dried over magnesium sulphate and evaporated to give 4-acetoxy-6-t-butyldimethylsilyloxymethyltetrahydro pyran-2-one (0.6 parts).
