Reaction Steps

To a solution of 6-bromopicolinaldehyde (1.07 g, 5.74 mmol) in dioxane (30 mL) at ambient temperature was added 3-chloro-4-fluorophenylboronic acid (1.00 g, 5.74 mmol), 2M cesium carbonate (8.60 mL, 17.2 mmol) and 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (0.234 g, 0.287 mmol). The mixture was degassed (3× vacuum/purge N2), then heated at 80° C. overnight. After cooling to ambient temperature the mixture was concentrated and the residue was partitioned between water and CH2Cl2. The organic extract was concentrated and purified by chromatography (10% ethyl acetate:hexanes) to provide the title compound. MS (DCI+) m/z 236 (M+H).
