실험 절차

Bromo[4-(ethyloxy)-4-oxobutyl]zinc (0.5 M in THF, 26 ml) was added dropwise to a solution of 1-bromo-5-isoquinolinecarbonitrile (D38; 1 g) and tetrakis(triphenylphosphine)palladium(0) (20 mg) in THF (5 ml). The resulting solution was heated to reflux for 3 hours. The solvent was evaporated in vacuo and the residue was dissolved in DCM (50 ml). The organic solution was washed with 0.5 M aq. NaOH (15 ml), followed by washing with water and brine. The organic phase was dried over anhydrous sodium sulphate. The dried solution was filtered and the filtrate was concentrated. The residue was purified by column chromatography to give the title compound (0.65 g). δH (CDCl3, 400 MHz): 1.28 (3H, t), 2.20 (2H, m), 2.50 (2H, m), 3.41 (2H, m), 4.16 (2H, q), 7.71 (1H, dd), 7.93 (1H, d), 8.12 (1H, dd), 8.54 (1H, d), 8.63 (1H, d). MS (ES): C16H16N2O2 requires 268. found 269.1 (M+H+).
