Procedure

A mixture of 5-bromo-7-chloro-3,4-dimethyl-1H-pyrrolo[2,3-c]pyridine (610 mg, 2.34 mmol), diethylphenyl boronic acid (500 mg, 2.81 mmol), Pd(PPh3)4 (140 mg, 0.12 mmol) and Na2CO3 (2M, 5 mL) in toluene (30 mL) is degassed, and stirred at 86° C. overnight. The mixture is diluted with EtOAc and washed with water and brine. The organic layer is dried over MgSO4 and concentrated under reduced pressure. Chromatography of the residue on silica gel (Hexane/EtOAc, 4:1) gives the titled compound. 1H NMR: (CDCl3) 9.10 (1H, br), 7.27 (1H, t, J=8.0 Hz), 7.14 (2H, d, J=8.0 Hz), 7.00 (1H, s), 2.46 (3H, s), 2.32 (3H, s), 2.27 (4H, q, J=7.5 Hz), 1.01 (6 H, t, J=7.5 Hz).
