Abstract

Un procedimiento de preparación de amidas aciladas del ácido {al}- aminocarboxílico directamente a partir de aminonitrilos con alto rendimiento y pureza. El procedimiento implica la acilación del aminonitrilo con un haluro de acilo bajo condiciones de Schotten- Baumann, y la hidrólisis del nitrilo resultante para obtener una amida. La amida acilada de ácido aminocarboxílico resultante precipita y puede aislarse mediante filtración con gran pureza.
