Procedure

9.22 parts of cyanuric chloride are suspended in 150 parts of ice-water. The pH is brought to 5 with 1 N sodium hydroxide solution and the temperature is kept at 0 to 2° C. A neutral solution of 29.80 parts of the copper complex of 5-amino-3-[3-phenyl-5-(2-carboxy-5-sulfophenyl)-1-formazano]-4-hydroxybenzenesulfonic acid in 250 parts of water is added to this suspension at 0 to 3° C. During the addition the pH is kept at 5 with a 2 N sodium hydroxide solution. After the addition the mixture is stirred at 0 to 3° C. and pH 5 for about a further 2 hours. A solution of 5-[4,6-dichloro-1,3,5-triazin-2-ylamino]-3-(3-phenyl-5-(2-carboxy-5-sulfophenyl)-1-formazano]4-hydroxybenzenesulfonic acid is obtained.
