实验步骤: 1-(4-nitro-phenyl)-propan-2-one (150 mg) was dissolved in methanol (5 ml) and then Pd/C (50 mg) was added. The resulting reaction mixture was stirred for 10 hr at room temperature under hydrogen pressure. The reaction mixture was filtered over celite and the filtrate evaporated. Purification by column chromatography over silica gel using ethyl acetate and hexane (1:9) as eluent gave 1-(4-amino-phenyl)-propan-2-one (60 mg, 48%). The resulting reaction mixture The reaction mixture was filtered over celite the filtrate evaporated Purification by column chromatography over silica gel

实验步骤: To a solution of 1-(4-aminophenyl)acetone (1.13 g, 7.57 mmol) and pyridine (1.84 ml, 22.7 mmol) in tetrahydrofuran (50 ml) was added 2,2,2-trichloroethyl chloroformate (1.57 ml, 11.4 mmol) with ice-cooling, and the mixture was stirred for 1 hour with ice-cooling and then at room temperature for 1 hour, the reaction mixture was poured into ice-water and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane: ethyl acetate=1:1) to obtain the desired product (1.44 g, 58.4%) as an oil. cooling cooling at room temperature for 1 hour the mixture was extracted with ethyl acetate The extract was washed with water dried over anhydrous magnesium sulfate the solvent was distilled off under reduced pressure The residue was purified by silica gel column chromatography (hexane: ethyl acetate=1:1)
