Procedure

5-Bromo-4-chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.660 g, 1.78 mmol), 3-fluorophenylboronic acid (0.298 g, 2.13 mmol), Pd(PPh3)4 (0.103 g, 0.0888 mmol) and 10% K2CO3 (aq., 3.70 mL, 2.66 mmol) were added to an argon degassed solution of 2:1 toluene:EtOH (6 mL). The reaction was then heated to 80° C. for 18 hours. The reaction was then diluted with water and extracted with DCM. The organic fractions were dried, filtered, concentrated, and purified by column chromatography (1:1 hexanes:DCM) to give 4-chloro-5-(3-fluorophenyl)-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.508 g, 73.9% yield).
