5-(2-tert-Butoxycarbonylethenyl)furan-2-carboxylic acid benzyl ester → 5-(2-Tert-butoxycarbonylethyl)-furan-2-carboxylic acid

Participants

Reaction Steps

5-(2-tert-Butoxycarbonylethenyl)furan-2-carboxylic acid benzyl ester (0.97 g, 2.80 mmol) was dissolved in methanol (50 mL), 10% palladium/carbon (0.1 g) was added, and the mixture was stirred at room temperature for 2 hours under a hydrogen atmosphere. After completion of the reaction, palladium/carbon was removed by celite filtration, and the solvent was evaporated under reduced pressure to give the title compound (0.66 g).
