실험 절차

To a degassed solution of 1.3 mL DMF at room temperature containing (S)-5-ethynyl-N-[methyl(oxo)phenyl-λ6-sulfanylidene]nicotinamide (63 mg, 0.22 mmol), 4-iodophenol (121 mg, 0.55 mmol), and triethylamine (0.09 mL, 0.66 mmol) was added dichlorobis(triphenylphosphine)palladium(II) (15 mg, 0.022 mmol) and copper(I)iodide (4 mg, 0.022 mmol). After proceeding for 1 hour the reaction was partitioned between EtOAc and H2O. The mixture was filtered to remove an insoluble brown precipitate and the EtOAc layer was washed with H2O, brine, dried with anhydrous Na2SO4 and rotary evaporated. The brown film was chromatographed eluting with CHCl3/EtOAc to give a yellow solid which was recrystallized from CHCl3/hexane to give the title compound as an off-white solid (38 mg, 45%).
