Reaction Steps

Methyl difluoroacetate (5 g, 45 mmol) in acetonitrile (50 ml) was reacted with ethanolamine (2.66 ml, 45.4 mmol) at ambient temperature for 24 hours. The solvent was evaporated and the residual oil was purified by chromatography on silica gel, eluting with dichloromethane:methanol (96:4) then dichloromethane:methanolic ammonia (94:6) to yield 2,2-difluoro-N-(2-hydroxyethyl)acetamide (6.18 g, 98% yield):
