A mixture of dibenzyl trans-cyclobutane-1,3-dicarboxylate (100 mg, 0.31 mmol) and 10% palladium-carbon (10 mg, 0.09 mmol, 50%, wet) in MeOH (2.0 mL) was stirred at room temperature for 5 hr under hydrogen atmosphere (1 atm). The catalyst was removed by filtration, and the filtrate was concentrated under reduced pressure to give crude trans-cyclobutane-1,3-dicarboxylic acid as a colorless oil.
