An improved method for the synthesis of substituted formylamines and substituted amines via an accelerated Leuckart reaction. The Leuckart reaction is accelerated by reacting formamide or N-alkylformamide and formic acid with an aldehyde or a ketone at a preferred molar ratio that accelerates the reaction. The improved method is applicable to various substituted aldehydes and ketones, including substituted benzaldehydes. An accelerated method for the hydrolysis of substituted formylamines into substituted amines using acid or base and a solvent at an elevated temperature. The improved method is useful for the accelerated synthesis of agrochemicals and pharmaceuticals such as vanillylamine, amphetamine and its analogs, and formamide fungicides.
