Reaction Steps
To a solution of 92 mg (0.24 mmol) of 3-(2,4-dichlorophenyl)-5-(1,1-dimethylethyl)-4-[(3-pyridyl)carbonyl]isoxazole in 5 mL of ethanol at 0° C. was added 20 mg (0.53 mmol) of sodium borohydride. After 2 hr, the reaction mixture was poured into water, and the product was extracted several times with ethyl acetate. The combined ethyl acetate fractions were washed with saturated sodium chloride and dried over magnesium sulfate. The drying agent was filtered off, and the ethyl acetate was removed by rotoevaporation. The crude product was purified by prep TLC to yield 68 mg (0.18 mmol) 3-(2,4-dichlorophenyl)-5-(1,1-dimethylethyl)-4-[(3-pyridyl)hydroxy-methyl]isoxazole. 1H NMR (CDCl3): δ 1.52 (s, 9), 6.14 (br s, 1), 6.86 (d, 1), 7.38 (m, 1), 8.27 (br s, 1) and 8.33 ppm (m, 1). MS m/z: 377.0 (M+H).
