반응 단계
24.6 g (168 mmol) 1-ethoxy-4-ethynyl-benzene, 52.8 g (176 mmol) [1-(4-Bromo-phenyl)-ethyl]-carbamic acid tert-butyl ester (50.2) and 42.6 mL (307 mmol) TEA are added to 400 mL ACN. The mixture is warmed to 65° C. 8.84 g (7.65 mmol) Pd(PPh3)4 and 2.91 g (15.3 mmol) CuI are added and the reaction mixture is stirred at reflux for 2 h. The mixture is cooled to r.t. and the solvent is removed in vacuo. The crude product is purified by column chromatography (hexane/EtOAC 9:1→3:1).
