実験手順
Triflic anhydride (1.1 ml, 6.6 mmol) was added to a cold (0° C.) solution of 2,2-difluoro-3-phthalimido-1-propanol (1.4 g, 6 mmol), pyridine (0.5 ml, 6.6 mmol) in anhydrous dichloromethane (30 ml). The mixture was stirred 1 h at 0° C. and, after usual work-up, the product was purified by flash chromatography on silica gel (ethyl acetate:hexane; 20:80) (1.7 g, 75%).
