Procedure

To a solution of methyl 5-ethenyl-2-furancarboxylate (1.3 g, 8.54 mmol) in methanol (15 ml) was added PdOH2 (0.240 g, 1.71 mmol). The reaction mixture was hydrogenated at 1 atm (balloon) for 1 h. The solution was then purged with N2, filtered through Celite and concentrated affording methyl 5-ethyl-2-furancarboxylate (1.2 g, 7.16 mmol, 84% yield) as a clear oil which was used without further purification: LCMS (ES) m/e 155 (M+H)+.
