Procedimiento

0.48 g of 3-amino-2-chloro-6-methylphenol hydrochloride is added to 0.8 g of N,N-dipentylbenzene-1,4-diamine dihydrochloride in solution in 5 ml of water and 40 ml of ethanol. The pH is adjusted to 9.5 with 20% ammonium hydroxide and then 1.7 ml of 9% aqueous hydrogen peroxide solution are added. The mixture is left stirring at ambient temperature for 5 hours and then the precipitate formed is filtered off. 0.72 g of 3-amino-2-chloro-4-{[4-(dipentylamino)phenyl]imino}-6-methylcyclohexa-2,5-dien-1-one (1o) is thus obtained.
