Reaction Steps

0.02 mole (0.246 g) 3-amino-6-methyl phenol is dissolved in 30 cc water to which 5 cc ammonia 22° Be were added. To this solution there is added 0.02 mole (0.332 g) 2,5-dimethoxy benzoquinone diimine from the first stage in solution in 60 cc water. The mixture is agitated for 20 minutes. Thereafter the reaction mixture is filtered off, yielding 0.125 g of said indoaniline which exhibits a melting point of 104°.
