Synthesis of 2-aminothiazoles through Hantzsch method involves the use of bromine. An 2-aminothiazole system 6-[2-aminothiazol-4yl]-2-furylchromone has been synthesized green chemically from 6-chloroacetyl-2-furylchromone and 6-acetyl-2-furylchromone during present study. The structures of new compounds were elucidated on the basis of IR and PMR-spectra.
