Procedure

Following reductive amination General Procedure AA above and using 1,4-benzodioxa-6-amine (Aldrich) and methyl pyruvate (Aldrich), N-(3,4-ethylenedioxyphenyl)alanine methyl ester was prepared. The methyl ester was then transesterified following General Procedure AQ above using iso-butanol to provide the title compound. Purification was by preparative plate chromatography.
