Alkylations of the stable diethyl N-(diphenylmethylene) aminomethylphosphonate (1) under solid-liquid phase-transfer catalysis (PTC) with or without solvent to give N-(diphenylmethylene) aminomethylphosphonic esters 2 are described. Acidic hydrolysis of 2 afforded diethyl (1-aminoalkyl)phosphonates 3 in good yields.
