3-AMINO-4-BROMO-1H-INDAZOLE Usage And Synthesis

Uses

Microwave heating of 2-halobenzaldehydes or 2-haloacetophenones with phenylhydrazines at 160°C for 10 min quantitatively yielded the arylhydrazones, which were further cyclized to give 1-aryl-1H-indazoles via CuI/diamine-catalyzed N-arylation under microwave heating (160°C, 10 min). Good to excellent yields were observed for 2-iodo, 2-bromo, and 2-chloro benzaldehydes or acetophenones.
