A process for reducing nitryl with unstable guanyl on para-position of benzene ring into azyl features that active metal reacts on organic acid and solvent at ordinary temp. and pressure to reduce N-(2 or 3-M, 5 or 6-M',4-nitrophenyl)-N',N'-dimethyl acetamidine into N-(2 or 3-m, 5 or 6-M', 4-aminophenyl)-N',N'-dimethyl acetamidine, where M=H,-R,-OR,-COOR (R=H, C1-C6); and M'=H,-R,-OR,-COOR (R=H, C1-C6). Its advantages include reduced by-reaction and high reducting rate up to 80%-95%.
本发明是将苯环上对位带有不稳定脒基的硝基还原为氨基的方法,采用活泼金属,如:锌或锡,与有机酸和适当的溶剂,在常温、常压下发生反应,将N-(2或3-M,5或6-M',4-硝基苯基)-N',N'-二甲基乙脒还原为N-(2或3-M,5或6-M',4-氨基苯基)-N',N'-二甲基乙脒,其中M=H,-R,-OR,-COOR(R=H,C1-C6),M'=H,-R,-OR,-COOR(R=H,C1-C6),减少了副反应,使还原收率达到80%以上,最高可达95%以上,更适用于工业化生产。
