A mixture of 4 gm of 2-chloro-4-nitro-3-phenoxy-1-(4-cyano-phenoxy)-benzene, 10 ml of dioxane and 2 gm of allylamine was allowed to stand at room temperature for 30 hours. Thereafter, the dioxane was distilled off, the residue was taken up in chloroform, the resulting solution was extracted with dilute sodium hydroxide, the organic phase was dried with sodium sulfate, the chloroform was distilled off, and the residue was recrystallized from ethanol. 3.5 gm (97.2% of theory) of the yellow crystalline title compound, m.p. 85°-87° C., were obtained.
