Yield: 60%
Reaction Conditions:
Stage #1:4-nitro-aniline with hydrogenchloride;sodium nitrite in water at 0 - 5; for 0.75 h;
Stage #2:sodium salicylate in water at 0 - 5; for 2 h;Alkaline conditions;
Steps:
General procedure: Synthetic procedures. Aromatic amine (1a-i) (0.01 mol) was dissolved in 1:1 ratio of conc. HCl and water. Sodium nitrite solution (0.02 mol/mL) was added to the reaction mixture dropwise with continuous stirring. The reaction mixture was stirred for 45 min. at a temperature of 0-5 oC. The diazotization step was followed by coupling of the diazotized amines by drop wise addition to the solution of sodium salicylate (0.01 mole of salicylic acid dissolved in 0.02 mol/mL solution of sodium hydroxide). The reaction was stirred at 0-5 oC for 2 hours under alkaline conditions. The conjugates of salicylic acid and aromatic amines (3a-i) were obtained as orange to red powders after the pH was neutralized to 6-7.
