摘要：
An efficient synthesis of 5,7-dimethylpyrazolo [3',4' :4,5]thiazolo[2,3-c]-1,2,4-triazole (2), an analogue of tricyclazole, was achieved by treatment of 4-(4'-amino-1',3'-dimethylpyrazol-5'-yl)-1,2,4-triazole-3-thione (7) with sodium nitrite in acidic medium followed by irradiation with UV light.
