To a nitrogen gas purged mixture of 5-chloro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrrolo[2,3-b]pyridine (231 mg, 0.565 mmol), (R)-2-(5-bromopyridin-3-ylamino)-3-methyl-N-(2,2,2-trifluoroethyl)butanamide (200 mg, 0.565 mmol), and Na2CO3 (847 μl, 1.694 mmol) in DME (3765 μl) was added Tetrakis (131 mg, 0.113 mmol). The reaction mixture was heated at 100° C. in a sealed microwave vessel for 1 h. Water (10 mL) was added and the mixture was extracted with ethyl acetate (2×20 mL). The combined organic extracts were dried with sodium sulfate, and concentrated under reduced pressure. Purification of the residue on silica (0-5% methanol/ethyl acetate, 25 gm silica) to give 232 mg foam, (2-1a).
