The synthetic route is as follows.
52 grams of 3 amino BENZOTRIFLUORIDE is mixed with 50 grams of 2 methyl 2 butanol and 200 mis of water are added, followed by 38 grams of sulfuric acid 96%. The mixture is iced to 5C and diazotized by the addition of 55 grams of a 40% solution of sodium nitrite. When the solution has become clear excess nitrous acid is reduced with SULFAMIC acid. This diazo is then added to a solution of 38 grams of 2 amino para cresol which has been dissolved in a mixture of 100 grams of 2 methyl 2 butanol and 100 grams of an aqueous solution containing 0.3 equivalents of naphthalene SULFONIC acids to which 1 gram each of acrylic acid and butyl methacrylate have been added as free radical suppressors. Coupling proceeds quickly at 5-10C and is brought to completion by the addition of sufficient sodium acetate solution to raise the pH to 2.5. When the azo coupling is complete 150 grams of toluene and 55 grams of hydrochloric acid 32% is added to the reaction. 60 grams of a 40% solution of sodium nitrite is now added to diazotize the amino azo compound. When this reaction is complete 0.3 molar equivalents of a composition made by condensing 0.3 equivalents of 3 amino phenol and 0.6 equivalents of 2 ethyl hexyl glycidyl ether dissolved as an 80% solution in toluene is added to the system. Coupling proceeds readily with the formation of a magenta red bisazo dye. The coupling is now adjusted to pH 9 by the addition of aqueous ammonia and heated to 60C. 0.3 molar equivalents of nickel chloride are now added to the system together with sufficient ammonia to stop the pH falling below 8.0. Formation of the metal complex is essentially instant as determined by TLC. 60 grams of 2 ethyl hexoxy propylamine is now added to the system and after a few minutes stirring agitation is stopped and the dye layer allowed to separate as an upper phase. The dye is then dried under vacuum to 110C and brought to a total weight of 700 grams with n-propanol. The product is a violet black with very good light fastness and solvent compatibility.
