3-(苄氧基)-4-甲基苯胺

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a stirred solution of 3-benzyloxy-4-methylnitrobenzene (1.1 g, 4.4 mmol) in tetrahydrofuran (25 mL) and methanol (50 mL) was added nickel acetate tetrahydrate (2.2 g, 8.7 mmol). The solution was cooled to 0° C. and sodium borohydride (0.66 g, 17.4 mmol) was added in small portions. After gas evolution had ceased, the solvents were removed in vacuo and the residue was partitioned between ethyl acetate and concentrated ammonium hydroxide. The layers were separated and the organic phase was washed with ammonium hydroxide followed by saturated aqueous sodium chloride solution, dried (magnesium sulfate), filtered, and concentrated In vacuo to give 0.9 g (97%) of the title product as an off-white solid. the solvents were removed in vacuo the residue was partitioned between ethyl acetate and concentrated ammonium hydroxide The layers were separated the organic phase was washed with ammonium hydroxide dried (magnesium sulfate) filtered concentrated In vacuo
