Reaction Steps

A vial charged with 2-fluoropyridin-3-ylboronic acid (0.156 g, 1.105 mmol), palladiumtetrakis (0.043 g, 0.037 mmol), potassium carbonate (0.255 g, 1.842 mmol), and 7-bromo-3-(2-methoxy-2-methylpropoxy)-5′H-spiro[chromeno[2,3-b]pyridine-5,4′-oxazol]-2′-amine (0.160 g, 0.368 mmol) was dissolved in 3 mL THF and 0.5 mL water and was heated to 110° C. 2 hours. The reaction mixture was diluted with EtOAc and dried over MgSO4. The organcis were concentrated then purified directly by column chromatography yielding 7-(2-fluoropyridin-3-yl)-3-(2-methoxy-2-methylpropoxy)-5′H-spiro[chromeno[2,3-b]pyridine-5,4′-oxazol]-2′-amine.
