Procedure

2.6 g 4,5-diamino-3-methyl-1-phenyl-1H-pyrazole dihydrochloride were dissolved in a mixture of 30 ml water and 30 ml ethanol. The pH of the resulting solution was then adjusted to 9 with concentrated ammonia. Subsequently the reaction mixture was stirred for 17 hours with a gasifying stirrer. The precipitated dye compounds was separated by filtration, washed with water and dried. The yield amounted to 1.2 g.
