실험 절차

To the DMF (2 ml) solution of 2-(1,1-dimethylprop-2-ynyl)-4-methoxy-benzoic acid methyl ester (Compound AA3, 134 mg, 0.577 mmol) and N-(2-bromo-5-cyanophenyl)methanesulfonamide (Compound AA3, 167 mg, 1.05 eq.), copper iodide (9 mg, 0.08 eq.) and TEA (129 μl, 1.6 eq.) were added, degassed and flushed with nitrogen gas, added with dicholorobis(triphenylphosphine) palladium (20 mg, 0.05 eq.), and then degassed and flushed again with nitrogen gas. After stirring for 2 hr at 90° C., the reaction solution was added with water, extracted with ethyl acetate. The organic layer was washed with an brine and dried over magnesium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were purified by silica gel column chromatography (ethyl acetate/hexane) to obtain the title compound (white solid, 152 mg, 62%).
