Reaction Steps

A mixture of diethyl 4-aminobenzylphosphonate (10 g) and diethyl benzylmalonate (24 g) was stirred at 160° C. for 24 hours. After cooling, the reaction mixture was purified by column chromatography on silica gel. Elution with chloroform-methanol (100:1, v/v) gave ethyl 2-(p-diethoxyphosphorylmethylphenylaminocarbonyl)-3-phenylpropionate (8.3 g, 45%) as crystals. Recrystallization from ethyl acetate-hexane gave colorless crystals having melting point of 115° to 116° C.
