To a cooled (5° C.) solution of 4-acetylmercaptotetrahydrothiopyran (1.91 g, 10.9 mmol) in dichloromethane (20 mL) was added methyltrifluoromethanesulfonate (1.3 mL, 11.5 mmol) dropwise over 30 minutes. The solvent was removed in vacuo to give 3.85 g (>100%) of the title compound as an oil which was used as such: 1Hmr (D2O) δ: 2.14-3.79 (m, 8H, ring protons), 2.39 (s, 3H, COCH3), 2.93 (s, 3H, SCH3) and 5.46 ppm (s, 1H, CHS).
