To a suspension of 2-amino-4-methyl-3,5-dinitrobenzonitrile (5) (3.129 g, 14.1 mmol) in anhydrous toluene is added N,N-dimethylformamide dimethyl acetal (4 mL). The resultant mixture is heated to about 100° C. for about 2.5 hours. The mixture is cooled to ambient temperature and the solvent is removed using a rotary evaporator. The residue is dried to provide crude N′-(6-Cyano-3-methyl-2,4-dinitro-phenyl)-N,N-dimethyl-methanimidamide (8) (3.85 g, 99% Yield) as a red solid.
