In a reaction flask, 6-fluoro-5-(5-methyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-pyridin-2-ylamine (137, 100 mg, 0.3902 mmol) was combined with 5-fluoro-2-methoxy-nicotinoyl chloride (151, 81.37 mg, 0.4292 mmol), 3.00 mL of tetrahydrofuran, and pyridine (0.06312 mL, 0.7804 mmol). The reaction was stirred at room temperature overnight, then poured into aqueous 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography, eluting with 1-5% methanol in dichloromethane. Appropriate fractions were combined and concentrated under vacuum to provide the desired compound (P-2168, 100 mg). MS (ESI) [M+H+]+=409.9.
