CuBr-catalyzed coupling reaction of 2-halobenzonitriles with hydrazine carboxylic esters and CuBr/4-hydroxy-pan class="smallcaps">lpan>-proline-catalyzed coupling reaction of 2-bromobenzonitriles with N鈥?arylbenzohydrazides proceed smoothly at 60鈥?0 掳C to provide substituted 3-aminoindazoles through a cascade coupling/condensation (or coupling/deacylation/condensation) process. A wide range of 3-aminoindazoles with substituents at both the 1-position and the phenyl ring part can be prepared from the corresponding coupling partners.
