Reaction Steps

Thionyl chloride (0.81 ml) was added to a solution of N-(4-hydroxy-2-butynyl)-2-hydroxy-2,2-diphenylacetamide (3.32 g) and N,N-dimethylformamide (6 drops) in chloroform (20 ml) at room temperature. The mixture was stirred at 40° C. for 1 hour, washed with water, dried over magnesium sulfate, and evaporated in vacuo. The residue was purified by column chromatography on silica gel with a mixture of chloroform and ethyl acetate (5:1) as an eluent to give N-(4-chloro-2-butynyl)-2-hydroxy-2,2-diphenylacetamide (4.12 g) as oil.
