Reaction Steps

A mixture of (6-bromo-pyridin-3-yl)-(1H-pyrrolo[2,3-b]pyridin-3-yl)-methanone (87, 160 mg, 0.53 mmol), 4-trifluoromethyl benzamide (51, 130 mg, 0.69 mmol), xanthphos (9 mg, 0.02 mmol), cesium carbonate (245 mg, 0.752 mmol), and tris(dibenzylideneacetone)dipalladium (0) (5 mg, 0.005 mmol) in toluene (2 mL) in a sealed tube was stirred at 110° C. for 1 hour. The reaction was quenched with water and extracted with dichloromethane. The organic layer was collected, washed with brine and dried over sodium sulfate. After removal of the solvent, the residue was purified with silica gel column chromatography eluting with ethyl acetate in hexane to provide the compound as an off-white solid (P-0067, 0.42 mg, 19%). MS (ESI) [M+H+]+=411.17.
