Procedure

26 ml of 6% aqueous hydrogen peroxide solution are added to a solution of 180 mg (0.001 mol) of 4-amino-2-chlorophenol sulfate and 253 mg (0.001 mol) of 4-butoxybenzene-1,3-diamine dihydrochloride in 2 ml of water and 2 ml of ethanol, and the solution is adjusted to pH 9.5 with 20% aqueous ammonia. After stirring for 5 hours at room temperature, the precipitate formed is filtered off, washed with water and dried. A brown powder is obtained.
