5-Bromo-4-chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyri dine (0.750 g, 2.01 mmol, see Example 6), 3-methoxyphenylboronic acid (0.321 g, 2.11 mmol), Pd(PPh3)4 (0.116 g, 0.100 mmol) and K2CO3 (4.20 mL, 3.02 mmol) were added to an Ar degassed solution of 2:1 toluene:EtOH (8 mL). The reaction was then heated to 80° C. overnight. The reaction was then poured into water and extracted with DCM. The organic fractions were dried, filtered, and concentrated to give the crude product. The crude product was purified (1:1 to 1:2 hexane:DCM) to give 4-chloro-5-(3-methoxyphenyl)-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.610 g, 75.8% yield).
