実験手順
To a stirred solution of 5-(tert-butyldimethylsilyloxy)-1H-indazole (5.3 g, 0.02 mol) in DMSO (50 mL) at 0° C., was added KOH (3.36 g, 0.06 mol) followed by iodine (10.2 g, 0.04 mol) portionwise. The mixture was stirred at room temperature for additional 10 minutes, then the reaction was quenched with 10% Na2S2O3 and diluted with water. The mixture was filtered and the filter cake was washed with water and dried to give 5-(tert-butyldimethylsilyloxy)-3-iodo-1H-indazole. The crude solid was used in the next step without purification. MS: (M+H)+=375.
