Procedure

Methanesulfonyl chloride (0.33 g, 2.87 mmol) was reacted with trans-2-diphenylmethyl-tetrahydropyran-5-ol 11 (0.38 g, 1.43 mmol) in the presence of triethylamine (0.22 g, 2.15 mmol) in methylene chloride (10 ml) to give trains-2-diphenylmethyl-tetrahydropyran-5-yl methanesulfonate 13 (0.39 g, 77.8%) as an oil (Procedure A).
