Reaction Steps

To a solution of 2-(3-bromophenylsulfonamido)-5-phenoxybenzenesulfonamide (241.5 mg, 0.5 mmol), 3,4-dichlorobenzeneboronic acid (190.8 mg, 1.0 mmol), tricyclohexyl phosphine (50 mg, 0.18 mmol) and potassium phosphate (340 mg, 1.6 mmol) in DMF (10 mL), was added Pd(OAc)2 (20 mg, 0.09 mmol). The reaction mixture was stirred at 80° C. for 7 h, diluted with 1N HCl and the product was extracted with ethyl acetate. The organic phase was separated, dried over sodium sulfate and concentrated in vacuo. The crude product was purified by flash column chromatography using ethyl acetate/hexane (1:1) to afford the title compound (42 mg, 15%).
