실험 절차

A 25 mL scintillation vial was charged with N-(2-boranyl-4-chloro-phenyl)-4-tert-butyl-benzenesulfonamide (90 mg, 0.27 mmol), tris(dibenzylideneacetone)dipalladium (18 mg, 0.02 mmol), 2-dicyclohexylphosphino-2′, 4′, 6′-triisopropylbiphenyl (24 mg, 0.05 mmol), 3-iodo-1H-indazole (65 mg, 0.27 mmol), saturated aqueous sodium bicarbonate (1 mL), and tetrahydrofuran (1.5 mL). The reaction was stirred at 80° C. under nitrogen overnight. The following day, the reaction was cooled to room temperature and diluted with 10 mL of ethyl acetate. The solution was subsequently washed with saturated aqueous NaHCO3 and brine, and then concentrated to dryness. The crude product was purified by flash chromatograph to yield 23 mg of product: MS (ES) M+H expected 441.1, found 441.1.
