On July 21, 2010, Kuang, Chunxiang; Zhang, Wensheng; Yang, Qing published a patent.Formula: C9H9N3 The title of the patent was Method for preparing 4-aryl-1H-1,2,3-triazole. And the patent contained the following:
The title method comprises adding (Z)-β-bromo arylethylene, DMF and NaN3 into tube in nitrogen gas ambient, stirring, adding Pd2(dba)3 and Xantphos, sealing, reacting at 105-115°C for 30-40 h to obtain 4-aryl-1H-1,2,3-triazole. The prepared 4-aryl-1H-1,2,3-triazole may be used as indoleamine 2,3-dioxygenase inhibitor. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Formula: C9H9N3
The Article related to triazole aryl preparation ido inhibitor, Heterocyclic Compounds (More Than One Hetero Atom): Other 5-Membered Rings, Two Or More Hetero Atoms and other aspects.Formula: C9H9N3
