실험 절차

To a degassed solution of 2.0 mL DMF at room temperature containing (R)-5-bromo-N-[methyl(oxo)phenyl-λ6-sulfanylidene]nicotinamide (105 mg, 0.31 mmol), 3-hydroxyphenylacetylene (73 mg, 0.62 mmol) and triethylamine (0.13 mL, 0.93 mmol) was added dichlorobis(triphenylphosphine)palladium(II) (22 mg, 0.031 mmol) and copper(I)iodide (3 mg, 0.016 mmol). The reaction was stirred at room temperature for 1.5 hours. Additional 3-hydroxyphenylacetylene was added (30 mg, 0.25 mmol) and the reaction was stirred at room temperature for an additional 3.5 hours. After proceeding for 5 hours the reaction was partitioned between EtOAc and H2O and the EtOAc layer washed with H2O, brine, dried with anhydrous Na2SO4 and concentrated. The residual dark oil was purified by chromatography (silica gel, CHCl3/EtOAc) and the product containing fractions were concentrated. The resulting solid was triturated with EtOAc/hexane to give the title compound as an off-white solid (37 mg, 32%).
