Versuchsvorschrift

To a mixture of 0.20 g (0.72 mmol) of 4,4-dimethyl-1,2,3,4-tetrahydro-N-(4-methylphenyl)-7-ethynylquinoline (Compound 3) and 0.39 g (1.5 mmol) of ethyl 2-fluoro-4-iodobenzoate were added 2.9 g (4.0 mL, 29 mmol) of triethylamine, 0.029 g (0.15 mmol) of copper(I) iodide, and 0.113 g (0.16 mmol) of bis(triphenylphosphine)palladium(II) chloride, consecutively. The resulting mixture was stirred at room temperature for 20 hours. Methylene chloride was added and the reaction was adsorbed onto silica gel. The product was obtained by flash chromatography (5% ethyl acetate in hexanes) followed by recrystallization in ethanol to give the title compound as orange crystals. PNMR (300 MHz, CDCl3) d 1.37 (6 H, s), 1.40 (3 H, t, J=7.1 Hz), 1.86 (2 H, t, J=6.0 Hz), 2.38 (3 H, s), 3.61 (2 H, t, J=6.0 Hz), 4.39 (2 H, q, J=7.1 Hz), 6.77 (1 H, d, J=1.7 Hz), 6.87 (1 H, dd, J=7.9, 1.7 Hz), 7.23-7.28 (7 H, m), 7.86 (1 H, t, J=7.8 Hz).
