실험 절차

tert-Butyl 6-benzyloxy-3-{4-cyclopropyl-5-[3-(2,2-dimethylpropyl)cyclobutyl]isoxazol-3-yl]hexanoate (980 mg), methanol (10 mL) and tetrahydrofuran (3 mL) were mixed. To the mixture was added 7.5 w/w % palladium on activated carbon (200 mg). The mixture was stirred at RT under hydrogen atmosphere (1 atm) for 5 hr. The catalyst was freshened up, and the mixture was stirred at RT under hydrogen atmosphere (1 atm) overnight. The 7.5 w/w % palladium on activated carbon was filtered off and the filtrate was concentrated in vacuo.
