A mixture of 14.2 gm of 2,3-dichloro-6-nitro-1-phenoxy-benzene, 10.2 gm of 2,5-dichloro-4-methylthiophenol, 5.0 ml of 10 N sodium hydroxide and 40 ml of dimethylsulfoxide was stirred for 5 hours at 100° C. and then allowed to stand overnight at room temperature. Thereafter, the reaction mixture was admixed with 400 ml of 1 N sodium hydroxide, and the product precipitated thereby was collected and recrystallized from 150 ml of ethanol. 20.5 gm (90% of theory) of the light yellow crystalline title compound, m.p. 138°-144° C., were obtained.
