Participants

Reaction Steps

14 parts of cyanuric fluoride are added dropwise to a neutral solution of 60 parts of the copper complex of 5-amino-3-[3-phenyl-5-(2-carboxy-5-sulfophenyl)-1-formazano]-4-hydroxy-benzenesulfonic acid and 5 parts of disodium hydrogen phosphate in 500 parts of at a temperature below 2° C., the pH being kept constant by addition of sodium hydroxide solution. A solution of 5-[4,6-difluoro-1,3,5-triazin-2-ylamino]-3-[3-phenyl-5-(2-carboxy-5-sulfophenyl)-1-formazano]4-hydroxybenzenesulfonic acid is obtained.
