실험 절차
A mixture of 2.4 g (0.011 mol) of 7,8-dihydro-1,3,5,8-tetramethyl-1H-imidazo[1,2-c]pyrazolo[3,4-e]pyrimidine and 5.6 g (0.022 mol) of chloranil in 400 ml of xylene is stirred under reflux four hours. The warm mixture is extracted with two 150 ml portions of 1N sodium hydroxide. The organic layer is separated, filtered, dried over MgSO4, and evaporated in vacuo. The solid residue is stirred in ether to give 1.2 g (50%) of the title compound, mp 198°-200°.
