A facile esterification of ketoximes and aldoximes in high yields can be performed using N-[3-(methylamino)propyl]-N′-ethylcarbodiimide hydrochloride (EDCI) in the presence of 4-(dimethylamino)pyridine (DMAP) as a catalyst at room temperature. The isolation and purification is very simple and for solid products, column chromatography is avoided.
