실험 절차

Ethyl 5-[4-(trifluoromethyl)phenyl]isoxazole-3-carboxylate (130 mg) was dissolved in ethanol (10 ml), cooled to 0° C., and sodium borohydride (26 mg) was added in portions to the stirred solution. The mixture was stirred at room temperature for 4 hours, then excess water added. Solvent was evaporated under reduced pressure, and the residue was purified by preparative thin layer chromatography, eluting with 5% methanol/ethyl acetate, to provide {5-[4-(trifluoromethyl)phenyl]isoxazol-3-yl}methan-1-ol, a compound of formula (24).
