実験手順

To a solution of 56 mg (0.13 mmol) of 5-(3-chlorophenyl)-3-(2-fluoro-5-trifluoromethyl-phenyl)-4-[(3-pyridyl)carbonyl]isoxazole in 2 mL of ethanol was added 24 mg (0.63 mmol) of sodium borohydride. After 2 hrs at room temperature, the reaction mixture was diluted with ethyl acetate. The solution was washed with saturated sodium chloride and was dried over magnesium sulfate. The drying agent was filtered off, and solvent was removed by rotoevaporation. The residue was purified by prepTLC to give 44 mg (0.098 mmol) of 5-(3-chlorophenyl)-3-(2-fluoro-5-trifluoromethylphenyl)-4-[(3-pyridyl)hydroxymethyl]isoxazole. 1H NMR (CDCl3): δ 6.01 (s, 1), 7.01 (m, 1), 7.83 (m, 1), 8.27 (m, 1), and 8.35 ppm (br s, 1). MS m/z: 449.0 (M+H).
