実験手順
To a solution of 6-methoxyisoquinolin-1(2H)-one (2.5 g, 14.27 mmol) in acetonitrile (10 ml) was added NBS (2.54 g, 14.27 mmol) at room temperature under argon atmosphere. The reaction mass was stirred at the same temperature for 2 hr. The precipitated solid was filtered to get crude compound (2 g, 55.2%). The crude compound was taken to the next step without further purification. 1H NMR (400 MHz, DMSO-d6): δ ppm 11.41 (s, 1H), 8.17-8.15 (d, J=8 Hz, 1H), 7.53 (s, 1H), 7.19-7.11 (m, 2H), 3.93 (s, 3H); MS: MS m/z 256.06 (M++2).
