A mixture of 28.4 gm of 2,3-dichloro-6-nitro-1-phenoxy-benzene, 21.6 gm of 2,4,5-trichloro-phenol, 10 ml of 10 N sodium hydroxide and 80 ml of dimethylsulfoxide was stirred for 6 hours at 100° C. Thereafter, the reaction mixture was admixed with 600 ml of 1 N sodium hydroxide, and the precipitated product was collected by suction filtration and recrystallized from 150 ml of ethanol. 31 gm (77.4% of theory) of the title compound, m.p. 112° C., were obtained. An additional amount of the product (about 6 gm) was obtained by evaporating the filtrate.
