실험 절차

2.9 g (0.01 mol) of 1-benzyl-3-propyl-5-nitroso-6-aminouracil are added to 60 ml of dimethylformamide together with 2.3 g (0.014 mol) of 1,4-benzodioxan-6-aldehyde, then 0.5 g (0.014 mol) of 1,1-dimethylhydrazine are added and the mixture is refluxed for 8 hours. After working up in the usual way, the crystalline residue is triturated with ethanol and filtered under suction. 1.0 g of the title compound is obtained in the form of yellow crystals, m.p. 290° C.
