7.175 parts of cuprous bromide are dissolved in 350 parts of bis(β-cyanoethyl) sulfide. 43.45 parts of 3-acetamido-4-(2'-chloro-4',6'-dinitrophenylazo)-N,N-diethylaniline are introduced, and the mass is brought to 130° C. During 1 hour 30 minutes, in an open reactor, a solution of 6.35 parts of sodium cyanide in 20 parts of water is added to the mixture and the mixture is stirred for 4 hours at 130°-135° C. The product formed is separated as in Example 1; 35.12 parts of 3-acetamido-4-(2'-cyano-4',6'-dinitrophenylazo)-N,N-diethylaniline are obtained. The yield is 82.5%.
