反应详情

NaBH4 (85 mg, 2.25 mmol) is added to a solution of 1-benzoyl-2,3-dihydro-1H-quinolin-4-one (from step C) in methanol (5 mL) at 0° C. The resulting mixture is stirred at room temperature. After 1 h, the reaction is quenched by 1 N HCl. The solvent is removed under vacuum. The residue is taken up in CH2Cl2 and washed by brine, and dried over anhydrous sodium sulfate. After concentration, the residue is purified by flash chromatography to give the title compound (380 mg, 84.8% yield for the two steps).
