Reaction Steps

To a glass microwave vial was added (4-(3-bromopyridin-2-yloxy)phenyl)(1H-imidazo[4,5-b]pyridin-2-yl)methanone (1.1099 g, 2.81 mmol), 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (1.180 g, 5.62 mmol), trans-dichlorobis(triphenylphosphine) palladium (II) (0.158 g, 0.225 mmol), and sodium carbonate (0.893 g, 8.43 mmol) in DMF (7.02 mL) and water (2.340 mL). The reaction mixture was stirred and heated in a Biotage Initiator microwave reactor at 120° C. for 20 min. The reaction mixture was diluted with water and extracted with DCM. The organic extract was washed with water, brine, dried with magnesium sulfate, filtered, and concentrated. The crude product was adsorbed onto a plug of silica gel and chromatographed through a Biotage pre-packed silica gel column (40M), eluting with a gradient of 1% to 5% MeOH in DCM, to provide (4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)(1H-imidazo[4,5-b]pyridin-2-yl)methanone. MS (ESI, pos. ion) m/z: 398.9 (M+1).
