실험 절차

3-Methyl-5-bromoisoquinoline (1.0 g, 4.5 mmol), tributylallyltin (1.6 mL, 5.0 mmol), and dichlrobis(tri-o-tolylphosphine)palladium (II) were combined in toluene (100 mL) and refluxed for 14 hours. The mixture was cooled, diluted with ethyl acetate, and washed twice with aqueous NH4Cl. The organic phase was separated, concentrated, and the residue was purified by chromatography (ethyl acetate:hexanes, 30:70) to provide the title compound. 1H NMR (300 MHz, d6-DMSO) 9.21 (s, 1H), 8.00 (d, 1H), 7.63 (m, 2H), 7.58 (m, 1H), 4.18 (s, 2H), 3.62 (s, 3H), 2.62 (s, 3H). MS (DCI/NH3) m/e 216 (M+H)+.
