Reaction Steps

Phosphorus pentachloride (1.082 g) is added over about 30 minutes into a mixture of 4-methyl-3,5-dinitrobenzamide (6) (1.04 g) in acetonitrile (20 mL, 15 g). The mixture is then heated to about 60° C. for about 4 hours. The solution is then cooled to ambient temperature and is slowly added to an ice and water mixture (20 mL). The mixture is cooled to about 5° C., whereupon ammonium hydroxide is added until a pH of about 8 is attained. The product that precipitates is filtered, washed with water (10 mL), and dried to provide 4-methyl-3,5-dinitrobenzonitrile (4) (0.72 g, 75% Yield).
