실험 절차

A mixture of 6-(6-bromo-[1,2,3]triazolo[4,5-b]pyrazin-1-ylmethyl)-7-fluoro-quinoline (2.0 g, 5.57 mmol), Pd(Ph3P)4 (0.64 g, 0.56 mmol) and tributyl(1-ethoxyvinyl)stannane (4.02 g, 11.14 mmol) in DMF (50 mL) was purged with nitrogen and then heated at 100° C. for 7 h. After removal of the solvent under reduced pressure, the residue was diluted with DCM, washed sequentially with aqueous KF and water, dried over Na2SO4 and concentrated in vacuo. The crude product was purified by column chromatography on silica gel with gradient (DCM:MeOH=50:1) to give the title compound as a white solid. 1H-NMR (400 MHz, DMSO-d6) δ ppm 9.11 (s, 1H), 8.93 (d, 1H), 8.40 (d, 1H), 8.15 (d, 1H), 7.83 (d, 1H), 7.54 (m, 1H), 6.22 (s, 2H), 5.50 (d, 1H), 4.73 (d, 1H), 4.02 (q, 2H), 1.40 (t, 3H). LCMS (method E): [MH]+=351, tR=5.42 min.
