5-Bromo-7-azaoxindole (0.75 g, 3.52 mmol), 2-tributyltinfuran (1.26 g, 3.52 mmol), tetraethylammonium chloride hydrate (1.94 g, 10.6 mmol) were combined and dissolved in acetonitrile (10 mL) at room temperature under an atmosphere of nitrogen. Bistriphenylphosphine dichloropalladium (II) (0.25 g, 0.35 mmol) was added and the reaction was warmed to 85° C. for 16 h. The reaction was cooled to room temperature and diluted with aqueous KF (10%, 60 mL). This was stirred for 20 minutes and then diluted with EtOAc (60 mL). The biphasic system was passed through celite, the layers separated, and the volatiles removed in vacuo. The resulting residue was triturated with diethyl ether and the solids were collected by filtration to afford a light yellow solid (0.28 g, 36% yield).
