Procedure

A mixture of N-(4-chloro-2-butynyl)-2-hydroxy-2,2-diphenylacetamide (0.70 g), sodium iodide (0.1 g) and 50% aqueous dimethylamine (2.2 ml) in 1.4-dioxane (7 ml) was stirred at room temperature overnight and then evaporated in vacuo. After an addition of saturated sodium bicarbonate aqueous solution, the mixture was extracted with ethyl acetate. The extract was 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 methanol (20:1) as an eluent to give N-(4-dimethylamino-2-butynyl)-2-hydroxy-2,2-diphenylacetamide (0.35 g).
