Trifluoromethanesulfonic anhydride (12.06 ml, 71.24 mmol), followed by 2,6-lutidine (11.42 ml, 81.42 mmol) were added to a solution of 2-fluoro-2-methylpropan-1-ol (6.25 g, 67.85 mmol) in DCM (146 ml) at −10° C. The reaction was stirred for 1 hr. then washed with 2N HCl (2×100 ml) and saturated NaHCO3 solution (2×100 ml). The organic phase was then cried over Na2SO4 and concentrated to give 2-fluoro-2-methylpropyl trifluoromethanesulfonate (12.89 g, 85%) as a red oil.
