In the present communication, we describe tandem combinations of Suzuki - condensation ring closure reactions to obtain a novel thieno[3 -,2 -:4,5]pyrido[2,3-d]pyridazine ring system. These compounds were studied by tandem mass spectrometry in detail and characteristic fragmentations were observed, which can be useful to confirm the presence of N -substituted pyridazine ring in synthesized compounds.
