HCID 11345542N-(2-naphthyl)alanine Ethyl Ester

Procedure

Following reductive amination General Procedure AA above and using 2-aminonaphthalene (Aldrich) and ethyl pyruvate (Aldrich), the title compound was prepared as a solid having a melting point of 52-56° C. The reaction was monitored by silica gel tlc (Rf=0.50 in 25% EtOAc/hexanes). Purification was by flash chromatography with silica gel using 25% EtOAc/hexanes as the eluant.
