Reaction Steps

1m (30 mg, 0.13 mmol) and 4-(3-mercapto-phenyl)-tetrahydro-pyran-4-carbonitrile (1n, 35 mg, 0.11 mmol) were dissolved in 1,4-dioxane (4 mL) and degassed with N2 for 10 minutes. iPr2NEt (0.04 mL, 0.22 mmol), Pd2dba3 (catalytic), and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (catalytic) 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 preparative HPLC to give the desired product, 1o.
