英文摘要：

An efficient and simple synthetic protocol for 1,3-diazaheterocycle-fused [ 1,2-c ]- 1,2,3-tria- zoles4 has been developed.The strategy involves the reaction of 2,4,6-triazido-1,3,5-triazine 2 and heterocy- clic ketene aminals （HKAs）3 in DMF medium at 90 ℃. Compound 2 has been used as the substrate efficiently providing the azide groups.This method has the advantages such as mild reaction conditions, operational simphcity and excellent yields （89%-93%）.
