반응 단계
Following general procedure F and using 2-cyclopropyl-6-ethynyl-4,4-dimethyl-1,2,3,4-tetrahydro-isoquinoline(Intermediate 27, 0.1 3 g, 0.571 mmol), 2-fluoro-4-iodo phenyl acetic acid ethyl ester (Reagent C, 0.16 g, 0.52 mmol), triethyl amine (0.8 mL), anhydrous tetrahydrofuran (2 mL), copper(I)iodide (0.051 g, 0.27 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.1 g, 0.14 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using 10% ethyl acetate in hexane as the eluent, 0.1 g of the title compound was obtained as an oil. It was further purified by preparative normal phase HPLC on a partisil-10 silica column using 10% ethyl acetate in hexane as the mobile phase (0.055 g, 24%).
