Procedure

6-Iodo-1H-quinolin-2-one (5.13 g, 18.9 mmol) and 4-(3-Mercapto-phenyl)-tetrahydro-pyran-4-carbonitrile (5f, 4.57 g, 20.8 mmol) were dissolved in 1,4-dioxane (160 mL) and degassed for 10 minutes with N2. iPr2NEt (6.6 mL, 37.9 mmol) was added, followed by Pd2dba3 (434 mg, 0.47 mmol), and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (548 mg, 0.95 mmol), and the reaction was degassed for another 10 minutes with N2. The reaction was then sealed and heated to 80° C. overnight. After cooling to room temperature, the reaction was filtered and concentrated, and the residue was purified by silica gel chromatography (0-100% MeOH in EtOAc) to give the desired product, 5g.
