Procedure

A finely powdered mixture of 15.5 grams (0.051 mole) of 3,5-dinitro-4-chloro-o-toluamide is heated with 12 grams (0.084 mole) of phosphorus pentoxide for 15 minutes at 300° C. to 350° C. The resulting nitrile is distilled from the reaction flask. Recrystallization of the solidified product from methanol gives the desired product as an analytically pure material.
