Abstract Two series of thiophene/benzothiophene-linked quinolinyl oxadiazoles condensed to the substituted N-benzothiazolyl acetamides have been synthesized via the Suzuki cross- coupling reaction. The ester derivative of 6-bromo-substituted quinoline was reacted via the Suzuki cross-coupling reaction with commercially available (benzo) thiophen-2-ylboronic acid at optimized temperature in 1, 2-dimethoxy ethane and water in the presence of ...
