HCID 22876174N-(2-naphthyl)alanine Methyl Ester

Procedure

Following reductive amination General Procedure A above and using 2-aminonaphthalene (Aldrich) and methyl pyruvate (Aldrich), the title compound was prepared. 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.
