Reaction Steps

1v (262 mg, 0.59 mmol), 4-(3-Mercapto-phenyl)-tetrahydro-pyran-4-carbonitrile (1w, 130 mg, 0.59 mmol), Pd2dba3 (14 mg, 0.01 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (17 mg, 0.03 mmol), and iPr2NEt (0.27 mL, 1.9 mmol) were dissolved in 1,4-dioxane (2 mL) and degassed with N2 for 10 minutes. The mixture was heated at 60° C. for 2 hours, then cooled to room temperature and concentrated. The residue was purified by silica gel chromatography to give the desired product, 1z.
