Özet

In this study, we synthesized new imidazo[2,1-b][1,3,4]thiadiazole derivatives containing benzothiazole group. To this end, we firstly obtained the benzo[d]thiazol-2-ylthio/oxy acetonitrile compounds (3a,b), the starting materials, in high yields (82% and 87%, respectively). Then, we synthesized the 2-amino-1,3,4-thiadiazole derivatives (4a,b) from the reaction of these nitrile derivatives (3a,b) with thio-semicarbazide in trifluoroacetic acid (TFA) (in yields of 83% and 84%). Finally, we synthesized the imidazo [2,1-b][1,3,4]thiadiazole derivatives (5-24) containing benzothiazole group, which are the target compounds, from reactions of 2-amino-1,3,4-thiadiazole derivatives (4a,b) with phenacyl bromide derivatives (in yields of 53%-73%).
