Hydrochloric Acid → 4-{[tert-Butyl(dimethyl)silyl]oxy}-3-fluorocyclohexyl methanesulfonate

Participants

Reaction Steps

To a stirred solution of 4-{[tert-butyl(dimethyl)silyl]oxy}-3-fluorocyclohexanol (500 mg, 2.01 mmol) and TEA (0.56 mL, 4.03 mmol) in DCM (5 mL) was added MsCl (0.28 mL, 3.6 mmol) at 0° C. The reaction mixture was warmed to room temperature, left to stir for 1 h, treated with sodium bicarbonate solution, and neutralized with 1 N HCl. The mixture was extracted with DCM. The combined organics were dried, and concentrated to afford the title compound.
