실험 절차

0.05 mole (10.55 g) methoxyparaphenylenediamine dihydrochloride is dissolved in 250 cc water and the pH is adjusted to 8 by addition thereto of ammonia. This solution is immediately added to 0.025 mole (3.5 g) 2-methyl 5-methylamino phenol previously dissolved in 250 cc water and to which 75 cc ammonia 22° Be have been added. 300 cc hydrogen peroxide are added to the mixture to 20 volumes and then the mixture is allowed to stand at room temperature for 4 hours. By filtering the mixture, there are then obtained 4.17 g of the above indoaniline in crystalline form, which, after washing with water and recrystallization from a mixture of acetone and water, exhibits a melting point of 125°.
