실험 절차
Then, 0.07 g of 5% palladium/carbon and 10 ml of a tetrahydrofuran solution containing 0.63 g of 4-((R)-1-trifluoromethylheptyloxycarbonyl)benzoic acid benzyl ester were stirred overnight at room temperature in a stream of hydrogen to decompose a benzyl protective group by hydrogenation. 5% palladium/carbon was removed using Celite as a filter aid, and the filtrate was concentrated. The concentrate obtained was purified by column chromatography to obtain 0.49 g of 4-((R)-1-trifluoromethylheptyloxycarbonyl)benzoic acid as a colorless liquid (gradually crystallized) (isolated yield: 98%).
