Reaction Steps

A mixture of ethyl 4,4-difluoro-3-oxobutanoate (5.0 g), butanimidamide hydrochloride (4.1 g) and sodium methoxide (28% methanol solution, 15 mL) in methanol (50 mL) was stirred overnight. The reaction mixture was diluted with ethyl acetate, washed with 1 M hydrochloric acid, dried over sodium sulfate and concentrated. The residue was purified by silica gel column chromatography to give the title compound as a pale yellow oil (5.6 g, 100%).
