A mixture of 2-bromo-5-chloro-1-(3-chlorobenzyl)-1H-pyrrolo[3,2-b]pyridine (0.59 g, 1.7 mmol, prepared as in Example 103, Step 2) and 4-(tributylstannyl)-1-trityl-1H-imidazole (1.0 g, 1.7 mmol, Synthonix) in toluene (32 mL) was degassed. Tetrakis(triphenylphosphine)palladium(0) (0.19 g, 0.17 mmol, Strem) was added, and the mixture was heated at 110° C. for 17 hours. Solvent was removed in vacuo, and the product was purified by flash chromatography, eluting with a gradient from 0-35% EtOAc in hexanes. Yield: (0.61 g, 62%).
