Reaction Steps

136 g of 4-bromo-N,N'-bisacetyl-1,3-phenylenediamine, prepared by bromination of N,N'-bisacetyl-1,3-phenylenediamine, are heated, in 300 ml of dimethylformamide, to 100° C. After adding 38 g of copper powder, the reaction mixture is stirred for 4 hours at 100° C. After cooling to room temperature, the mixture is freed from copper as indicated in Example 2. 72 g (75% of theory) of 2,2',4,4'-tetrakis-(acetylamino)-biphenyl of the formula ##STR32## are obtained.
