摘要：
Reaction of coumarin-3-carboxylic acid with 3,5-di mercapto-4-amino-s-triazole in POCl(3)to generate 3-(3-mercapto-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazol-6-yl)-2H-chromen-2-one (3). Reaction of 3 with different substituted phenacyl/benzyl/allyl bromides in anhydrous ethanol gave corresponding 3-(3-(phenacyl/alkyl/benzylthio)-[1,2,4]triazolo[3,4-b][1,3,4] thiadiazol-6-yl)-2H-chromen-2-ones 5. The structures of newly prepared compounds were confirmed by their analytic and spectral data.
