A solution of 17.4 g. (0.075 mol.) of 3,4 dinitrobenzoylchloride in 250 ml. of methylene chloride is treated at 0°-20° C with a solution of 11 g. (0.15 mol.) of diethylamine in 100 ml. of methylene chloride. The solution is kept at 20°-25° C for 2 hrs., the solvent is evaporated and the residue triturated with water. Recrystallization from methanol affords 4-(N,N-diethylcarbamoyl)-1,2-dinitrobenzene.
