実験手順
To a solution of 1-chloro-6-methoxyisoquinolin-4-ol (0.05 g, 0.239 mmol) in acetonitrile (5 ml) was added potassium carbonate (0.099 g, 0.716 mmol) followed by iodoethane (0.039 ml, 0.477 mmol) at room temperature. The reaction mass was stirred at the same temperature for 18 h. The solvent was evaporated under reduced pressure and the residue was diluted with water and extracted with dichloromethane. The organic layer was dried over anhydrous sodium sulfate, filtered and evaporated to get crude compound. The crude compound was purified by silica gel chromatography (10% ethyl acetate in pet ether) to get desired compound (0.015 g, 25.1%) as solid. 1H NMR (400 MHz, DMSO-d6): δ ppm 8.14-8.12 (d, J=8 Hz, 1H), 7.90 (s, 1H), 7.46-7.42 (m, 2H), 4.34-4.27 (q, J=8 Hz, 2H), 3.95 (s, 3H), 1.48 (t, J=10 Hz, 3H).
