2-Amino-5-nitrobenzonitrile → N'-(2-cyano-4-nitrophenyl)-N,N-dimethylmethanimidamide

Participants

Reaction Steps

A 40.8 g portion of 5-nitro-anthranilonitrile and 40 ml of N,N-dimethylformamide dimethyl acetal were heated on a steam bath for 2 hours. The solvents were removed at reduced pressure and the residue was taken up in methylene chloride. After passing this solution through Magnesol the solvent was removed. After washing with ether 50.8 g of N'-(2-cyano-4-nitrophenyl)-N,N-dimethylformamidine was obtained.
