Reaction Steps

1g (230 mg, 0.82 mmol) and 4-(3-Fluoro-5-mercapto-phenyl)-tetrahydro-pyran-4-carbonitrile (1h, 230 mg, 0.99 mmol) were dissolved in 1,4-dioxane (10 mL) and degassed with N2 for 10 minutes. iPr2NEt (0.35 mL, 2.0 mmol), Pd2dba3 (20 mg, 0.02 mmol), and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (24 mg, 0.04 mmol) were added, and the mixture was degassed with N2 for an additional 10 minutes. The reaction was heated to 80° C. overnight, then cooled to room temperature, concentrated, and purified by silica gel chromatography to give the desired product, 1k.
