실험 절차

A solution of cis-2-phenyltetrahydro-2H-pyran-4-ol (1 g) in DCM (20 mL) was cooled in an ice-salt water bath and treated with DIEA (2.2 g) and methanesulfonyl chloride (0.7 g) for 2 hours. The mixture was diluted with DCM (50 mL) and washed with water and brine. The organic layer was dried and concentrated. Preparative TLC provided 0.9 g of cis-2-phenyl-tetrahydro-2H-pyran-4-yl methanesulfonate.
