1,1′-Bis(diphenylphosphino)ferrocene palladium dichloride methylene chloride adduct (14 mg, 0.02 mmol) was added to a solution of 6-methoxy pyridine-2-boronic acid pinacol ester (135 mg, 0.57 mmol), 2-[(3-bromophenyl)sulfonylamino]benzenesulfonamide (150 mg, 0.38 mmol) (see Example 113a) and Na2CO3 (0.18 mg, 1.72 mmol) in THF:water, 10:1 (4 mL). The reaction mixture was heated in a microwave reactor at 120° C. for 20 min. Some DCM was added followed by brine and the aqueous layer was extracted twice with DCM. The combined organic layers were dried with Na2SO4 and after filtration and evaporation the crude was purified by preparative HPLC (XTerra MS C8 column, acetonitrile/ammonium acetate buffer) to give the title compound (30 mg, 19%) as a yellow oil.
