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

Participants

Reaction Steps

Following reductive amination General Procedure AA 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 AQ above and using iso butanol to provide the title compound as an oil. The reaction was monitored by silica gel dc (Rf=0.61 in 25% EtOAc/hexanes). Purification was by preparative plate chromatography with silica gel using 25% EtOAc/hexanes as the eluant.
