摘要：

The reactions of N-substituted 4-amino-3-benzyl-1,2,3-triazole-5-carboxamides with phosphorus oxochloride and dimethylformamide at 80 degreesC or with triethyl orthoacetate and acetic anhydride at 160 degreesC afforded 6-mono- or 5,6-disubstituted 1,2,3-triazolo[4.5-d]pyrimidin-7-ones in 30-85% and 65-90% yields, respectively.
