Reaction Steps
To a suspension of 4-methyl-3,5-dinitrobenzoic acid (3) (1.5 g) in acetonitrile (22.5 g, 30 mL) and triethylamine (0.87 g, 1.2 mL) at −10° C. is slowly added a solution of methylchloroformate (0.723 g, 0.6 m-L) in acetonitrile (2.25 g, 3 mL). The resulting mixture is agitated at −10° C. for about 1 hour, whereupon ammonia gas (excess) is bubbled though the mixture for about 30 minutes. The resultant mixture is allowed to age at about −5 to −10° C. for 12 hours, whereupon the mixture is added to a mixture of ice and water (100 mL). The solid that precipitates is filtered and dried to provide 4-methyl-3,5-dinitrobenzamide (6) (1.36 g, 91% Yield).
