실험 절차

5,6-Diamino-1-methyl-3-propyl-2,4(1H,3H)pyrimidinedione was prepared freshly from 6-amino-1-methyl-5-nitroso-3-propyl-2,4-(1H,3H)pyrimidinedione by ammonium sulfide reduction using the method of V. Papesch, M. Grove, and E. F. Schroeder (U.S. Pat. No. 2,602,795). This diamine (2.00 g, 10.0 mmol) was condensed with 4-formylcinnamic acid (1.76 g, 10.0 mmol) by the procedure of Example 2 to give the title compound as an ivory powder, after crystallization from N,N-dimethylformamide-water; mp>300° C. Analysis for (C18H18N4O4.1/5 DMF): C,60.54; H,5.30; N,15.94. Found: C,60.52; H,5.22; N,16.03.
