Abstract
A method of preparing acylated .alpha.-amino carboxylic acid amides directly from amino nitriles in high yield and purity. The method involves acylating the amino nitrile with an acyl halide under Schotten-Baumann conditions, and hydrolyzing the resulting nitrile to the amide. The resulting acylated amino carboxylic acid amide precipitates and can be isolated by filtration in high purity.
