Sodium borohydride → HCID 59675043, compound

Participants

Reaction Steps

To a solution of 50 mg (0.1 mmol) of 5-(2-chlorophenyl)-3-(2,4-dichlorobenzyl)-4-[(3-pyridyl)carbonyl]isoxazole in 15 mL of THF was added 21 mg (0.56 mmol) of sodium borohydride at room temperature. After 2 hrs, the solution was diluted with ethyl acetate, washed with saturated sodium chloride, and dried over magnesium sulfate. The drying agent was filtered off, and solvent was removed by rotoevaporation. The crude product was purified by prep TLC to give 39 mg (0.088 mmol) of 5-(2-chlorophenyl)-3-(2,4-dichlorobenzyl)-4-[(3-pyridyl)hydroxymethyl]isoxazole. 1H NMR (CDCl3): δ 3.91 (d, 1), 4.00 (d, 1), 6.97 (br s, 1), 7.64 (d, 1), 8.42 ppm (br m, 2). MS m/z: 445.0 (M+H).
