실험 절차

0.2 mole (4.5 g) 2-methoxy-5-methyl paraphenylenediamine dihydrochloride is dissolved in 200 cc water and the pH thereof is adjusted to 8 by the addition thereto of ammonia. This solution is immediately added to 0.02 mole (2.74 g) 3-amino-2,6-dimethyl phenol, previously dissolved in 200 cc water. To the resulting mixture there are added 60 cc ammonia 22° Be and 260 cc hydrogen peroxide to make 20 volumes. The mixture is allowed to stand at room temperature for four hours. On filtering the reaction mixture on a suction filter, then are obtained 3.1 g of said indoaniline in crystalline form, which after recrystallization from a mixture of pyridine and water, exhibits a melting point of 145°.
