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。
