Into a sealed tube was added tetrahydro-2H-pyran-4-carbaldehyde (0.25 g, 2.190 mmol), 3-bromo-2-fluoropyridine (0.321 g, 1.825 mmol), palladium(ii) acetate (0.016 g, 0.073 mmol), cesium carbonate (0.714 g, 2.190 mmol), water (1.644 μL, 0.091 mmol), BINAP (0.068 g, 0.110 mmol) in Dioxane (7.30 mL). The resulting mixture was heated to 100° C. overnight. More catalyst and ligand (palladium(ii) acetate (0.016 g, 0.073 mmol), binap (0.068 g, 0.110 mmol)) were added and the resulting mixture was heated to 113° C. until the starting material was completely consumed. Aqueous work up followed by DCM extraction. Purification by Biotage (0-100% MeOH/DCM) & prep-plate TLC (5% MeOH/DCM) produced product which was advanced to the next step.
