Participants

Reaction Steps

21.3 parts of N,N-dimethyl-N'-(4-chloro-3-cyano-thien-2-yl)-formamidine are introduced into 100 parts of 100% strength nitric acid, while cooling with ice. The mixture is stirred for 1 hour at room temperature, after which the product is precipitated by pouring the mixture onto ice water, and the precipitate formed is filtered off under suction, washed with water and dried to give 18.8 parts (73% of theory) of N,N-dimethyl-N'-(4-chloro-3-cyano-5-nitrothien-2-yl)-formamidine. Decomposition temperature: 254° C. (from glacial acetic acid).
