反应详情

2-Chloro-N-methyl-6-nitrobenzenamine (1.5 g, 8.0 mmol) was dissolved in a mixture of EtOH (15 mL) and H2O (15 ml). Iron powder (2.2 g, 40 mmol) was added followed by Acetic acid (0.55 mL, 9.6 mmol). The reaction was monitored by TLC, after 30 min, the reaction was completed. The reaction mixture was filtered over celite pad and the filtrate was neutralized by saturated NaHCO3 (10 mL). The product was extracted by EtOAc (2*10 mL), the organic layer was washed with brine (10 mL), dried over MgSO4 and concentrated to dryness to afford 920 mg of 6-chloro-N1-methylbenzene-1,2-diamine (Yield: 73%) as dark brown oil.
