To a vial containing 1,5-dimethyl-1H-pyrazol-3-amine (13.60 mg, 0.122 mmol), Pd2(dba)3 (4.67 mg, 5.10 μmol), Xantphos (5.90 mg, 10.20 μmol), and cesium carbonate (100 mg, 0.306 mmol) was added N,N-dicyclopropyl-6-ethyl-4-iodo-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (45.8 mg, 0.102 mmol) in DME (1020 μL). The reaction mixture was sparged with argon for 5 min, the vial was capped, and the reaction mixture was heated at 90° C. 1 h. The reaction mixture was diluted with dichloromethane and vacuum filtered through Celite. The filtrate was concentrated in vacuo. The crude residue was purified via flash column chromatography using an ISCO 12 g column eluting with 1-10% MeOH/CH2Cl2). N,N-Dicyclopropyl-4-(1,5-dimethyl-1H-pyrazol-3-ylamino)-6-ethyl-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (14 mg, 31.7% yield) was isolated as an off-white solid.
