Synthesis and characterization of new pyrazole-based thiazoles

ABSTRACT A series of new 5-(heteroaryldiazenyl)thiazole incorporating pyrazole moiety have been synthesized through coupling of the thiazole with the appropriate heteroaryldiazonium salts. The newly synthesized compounds were characterized by elemental analysis, spectroscopic (IR, 1H NMR, and Mass) data, and alternative synthesis whenever possible. GRAPHICAL ABSTRACT
