実験手順

NaBH4 (3.24 g, 85.60 mmol) was slowly added to a solution of 2′-nitroacetophenone NAP (3.74 g, 22.65 mmol) in a mixture of methanol (34 mL) and dioxane (22 mL). The reaction mixture was stirred at room temperature for one hour and then diluted with ethyl acetate (100 mL) and washed with water (25 mL). The organic layer was dried with Na2SO4, filtered, and concentrated in vacuo to yield 1-(2-nitrophenyl)ethanol dC.13a (3.49 g, 92%) as a white powder.
