Sodium borohydride → 1-Phenyl-1-[4-(4-pyridyl)-2-thiazolyl]methanol

関与物質

反応手順

To a solution of 1-phenyl-1-[4-(4-pyridyl)-2-thiazolyl]methanone (675 g, 0.0025 mol) in methanol (40 mL) was added sodium borohydride (300 mg, 0.0079 mol) in portions and the mixture allowed to stir at room temperature for one hour. The reaction mixture was concentrated, diluted with water, and extracted with ether (3×25 mL). The combined extracts were washed with brine, dried over magnesium sulfate, concentrated, and chromatographed. Recrystallization from hexane/ethyl acetate afforded 1-phenyl-1-[4-(4-pyridyl)-2-thiazolyl]methanol (300 mg, 45%). mp. 146°-147° C.
