Reaction Steps
5-Chloro-2-fluorophenylboronic acid (2.7 g, 15.48 mmol), 2-chloropyridin-4-amine (1.531 g, 11.91 mmol), sodium carbonate (5.96 ml, 11.91 mmol), and bis(triphenylphosphine) palladium chloride (0.836 g, 1.191 mmol) were combined in dioxane (54 mL) and refluxed for 3 hours. The reaction was cooled, the solvent removed in vacuo and the reaction mixture partitioned between brine and EtOAc. The organic layer was separated, dried over MgSO4 filtered and purified using NH silica column chromatography and a gradient of 5-95% EtOAc in hexanes to afford the title compound as a white solid (522 mg; 20%). ESI-MS: m/z 223.1 (M+H).
