Methyl pyruvate → N-(3,4-methylenedioxyphenyl)alanine Iso-butyl Ester

Participants

Reaction Steps

Following reductive amination General Procedure A above and using 3,4-methylenedioxyaniline (Aldrich) and methyl pyruvate (Aldrich), N-(3,4-methylenedioxyphenyl)alanine methyl ester was prepared. The methyl ester was then transesterified following General Procedure Q above and using iso-butanol to provide the title compound as an oil. The reaction was monitored by silica gel tlc (Rf=0.61 in 25% EtOAc/hexanes). Purification was by preparative plate chromatography with silica gel using 25% EtOAc/hexanes as the eluant.
