반응 단계
Add trifluoromethanesulphonic anhydride (1.12 mL, 6.8 mmol) to a solution of neopentylalcohol (0.5 g, 5.7 mmol) and 2,6-lutidine (0.7 mL, 6.8 mmol) in dichloromethane (10 mL) at −78° C. and stir for 1 hour. Add water to quench the reaction, separate the organic layer and extract the aqueous layer with dichloromethane. Combine the organic layers, dry (magnesium sulfate), filter, concentrate and purify (silica gel chromatography, eluting with 1:4 hexane:dichloromethane) to give the desired compound as an oil (0.9 g, 72% yield).
