실험 절차

To a solution of 0.097 g (0.40 mmol) of 4,4-dimethyl-2-isopropoxy-1,2,3,4-tetrahydro-7-ethynylquinoline (Compound 27) and 1.16 g (0.75 ml, 4.2 mmol) of ethyl 4-iodobenzoate in 3.0 ml of diethylamine which was degassed under argon for 15 min, was added 0.043 g (0.23 mmol) of copper(I) iodide and then 0.064 g (0.09 mmol) of bis(triphenylphosphine)palladium(II) chloride. The reaction was stirred at room temperature for 16 h. The reaction mixture was then concentrated. Purification by flash chromatography (1.5% EtOAc in hexane) gave the title compound as an oil. PNMR (CDCl3) d 8.00 (2H, d, J=8.2 Hz), 7.54 (2H, d, J=8.1 Hz), 7.32 (1H, s), 7.23 (2H, s), 5.40 (1H, p, J=6.3 Hz), 4.37 (2H, q, J=7.1 Hz), 2.24 (2H, s), 1.39 (3H, t, J=7.1 Hz), 1.32 (6H, d, J=6.2 Hz), 1.24 (6H, s).
