실험 절차
To a solution of 6-chloro-1H-indazole-4-carbonitrile (2.0 g, 11.26 mmol) in DMF (30 mL) was added KOH (1.89 g, 33.78 mmol) and I2 (5.72 g, 22.52 mmol). The mixture was heated at 50° C. overnight. The reaction mixture was quenched with EtOAc (200 mL) and water (100 mL). The organic layer was concentrated in vacuo to afford 6-chloro-3-iodo-1H-indazole-4-carbonitrile as white solid (2.01 g, 58.8%). MS (ESI): m/z=304 [M+1]+.
