Procedure
0.68 mmol of 2,3-diamino-5,6,7,8-tetrahydro-1H-pyrazolo[1,2-a]pyridazin-1-one methanesulfonate was dissolved in a mixture of water and ethanol (7.5 ml/1.5 ml). This solution was admixed with 0.68 mmol of 3-amino-2-chloro-6-methylphenol, then with 1.8 ml of concentrated aqueous ammonia, then with 9 ml of hydrogen peroxide.
