Sodium Sulfate → HCID 67418080, compound

Participants

Reaction Steps

To a solution of lithium aluminum hydride (92 mg, 2.42 mmol) in dry THF (20 mL), 3-[2-(2,4-dichlorophenyl)-5-isopropyloxazol-4-yl]-1-(4-hydroxy-3-methylphenyl)propan-1-one (1.01 g, 2.41 mmol) was gradually added while cooling with ice. The mixture was stirred for 1 hour, and further stirred at room temperature. The reaction mixture was again cooled with ice. To the mixture, a saturated aqueous sodium sulfate solution was dropwise added. After insoluble materials were filtered out, the solvent was removed under reduced pressure. The residue was extracted with ethyl acetate, washed with water (15 mL) containing a small amount of a 1M aqueous solution of hydrochloric acid, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure to obtain the desired compound (997 mg) as ocher yellow crystal (yield 98%).
