実験手順

A mixture of (S)—N-[methyl(oxo)phenyl-λ6-sulfanylidene]-5-[(trimethylsilyl)ethynyl]nicotinamide (54 mg, 0.15 mmol), 3-iodobenzoic acid (56 mg, 0.23 mmol), dichlorobis(triphenylphosphine)palladium(II) (11 mg, 0.02 mmol), triphenylphosphine (1.0 mg, 0.004 mmol) and triethylamine (0.073 mL, 0.53 mmol) in 1.5 mL DMF at room temperature was degassed using vacuum and a H2/N2 (1:1) mixture and then copper(I) iodide (2 mg, 0.01 mmol) added. The reaction was heated to 60° C. then tetrabutylammonium fluoride (1.0 M in THF, 0.15 ml) added over 3.5 minutes. After 25 minutes the reaction was partitioned between EtOAc and dilute AcOH. The EtOAc layer was collected and washed with H2O, brine, dried with anhydrous Na2SO4 and concentrated to a yellow solid. The solid was triturated with EtOAc at room temperature to give the title compound as a yellow solid (45 mg, 74%).
