反応手順

0.01 mole (2.11 g) methoxyparaphenylenediamine dihydrochloride is dissolved in 100 cc water and the pH thereof is adjusted to 8 by addition of ammonia. This solution is immediately added to 0.01 mole (1.37 g) 3-amino-2,6-dimethyl phenol, preliminarily dissolved in 100 cc water. There are added to this resulting mixture 30 cc ammonia 22° Be' and 130 cc hydrogen peroxide to make 20 volumes, and the mixture is allowed to stand at room temperature for four hours. On filtering the reaction mixture on a suction filter there are obtained 1.8 g of the above indoaniline in crystalline form which melts at 217°. After a recrystallization from a mixture of dimethylformamide and water, the said indoaniline exhibited the same melting point.
