実験手順

0.58 mmol of 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazol-1-one dimethane sulphonate was dissolved in a mixture of water and ethanol (7.5 ml/1.5 ml). This solution was admixed with 0.58 mmol of 2-methyl-1-naphthol, then with 1.8 ml of concentrated aqueous ammonia, then with 9 ml of hydrogen peroxide.
