Procedure

A solution of methyl 4-(4-benzylpiperazin-1-yl)but-2-enoate (10.2 g, 0.04 moles) in methanol was added to 20% palladium hydroxide on carbon and placed under 40 psi hydrogen gas for 7 h. The resulting solution was filtered through celite and evaporated to afford methyl 4-(4-benzylpiperazin-1-yl)butanoate (6.70 g, 97%). MS (ESI+) for m/z 187 (M+H)+.
