Five grams of 1-chloro-3,4-dimethyl-2,6-dinitrobenzene and 5.05 grams of di-n-propylamine are dissolved in benzene and the mixture is refluxed. The benzene is then removed from the mixture by boiling and toluene is added to the remaining residue. The thus-formed mixture is then refluxed, filtered, and the filtrate stripped in vacuo. The residue is treated with hexane and the mixture chilled in dry ice and acetone. The solid from the mixture is collected and dried, it has a melting point of 42° C. to 43.5° C. and is the desired product.
