实验步骤: To a solution of 4-[2-(2-methoxy-ethoxy)-1,1-dimethyl-ethyl]-phenylamine (5.8 g, 26 mmol) in H2SO4 (20 mL) was added KNO3 (2.63 g, 26 mmol) at 0° C. After addition was complete, the mixture was stirred at this temperature for 20 min and then poured into ice-water. The mixture was extracted with EtOAc (50 mL×3). The combined organic layers were washed with water and brine, dried over Na2SO4, and concentrated. The residue was purified by column chromatography (petroleum ether-EtOAc, 100:1) to give 4-[2-(2-methoxy-ethoxy)-1,1-dimethyl-ethyl]-3-nitro-phenylamine (5 g, 71%). After addition The mixture was extracted with EtOAc (50 mL×3) The combined organic layers were washed with water and brine dried over Na2SO4 concentrated The residue was purified by column chromatography (petroleum ether-EtOAc, 100:1)

实验步骤: A suspension of 1-[2-(2-methoxy-ethoxy)-1,1-dimethyl-ethyl]-4-nitro-benzene (8.1 g, 32 mmol) and Raney Ni (1 g) in MeOH (50 mL) was stirred under H2 (1 atm) at room temperature for 1 h. The catalyst was filtered off and the filtrate was concentrated to obtain 4-[2-(2-methoxy-ethoxy)-1,1-dimethyl-ethyl]-phenylamine (5.5 g, 77%). The catalyst was filtered off the filtrate was concentrated
