  An Efficient Synthetic Process for Scale-Up Production of 4,5-Diamino-2-(trifluoromethyl)benzonitrile and 5-Bromo-3-(trifluoromethyl)benzene-1,2-diamine

  摘要：

  Starting from 4-amino-2-(trifluoromethyl)benzonitrile (6), an efficient and nonchromatographic process was developed for multihundred gram production of 4,5-diamino-2-(trifluoromethyl)benzonitrile (1) in 73% yield and 98 HPLC area% purity over four synthetic steps. The same synthetic strategy was applied to 4-bromo-2-(trifluoromethyl)aniline (7) that afforded 5-bromo-3-(trifluoromethyl)benzene- 1,2-diamine (5) in 81% overall yield and 99% HPLC area% purity.
