실험 절차

A solution of 3-(3-chloro-4-methoxyphenyl)-6-methoxyisoquinolin-1-ol (1.2 g, 3.80 mmol) in POCl3 (5.31 ml, 57.0 mmol) was refluxed for 4 h. The reaction mixture was concentrated. The residue was dissolved in DCM and the pH was adjusted to 7 with 4N NaOH. The organic phase was collected and dried over sodium sulfate, filtered, then concentrated under vacuum to give 1-chloro-3-(3-chloro-4-methoxyphenyl)-6-methoxyisoquinoline (1.2 g, 95% yield). δ ppm 1H NMR (400 MHz, CHLOROFORM-d) δ 8.22 (d, J=9.3 Hz, 1H), 8.15 (d, J=2.3 Hz, 1H), 8.02 (dd, J=8.7, 2.4 Hz, 1H), 7.27-7.24 (m, 1H), 7.13 (d, J=2.5 Hz, 1H), 7.05 (d, J=8.5 Hz, 1H), 3.99 (s, 6H); MS: MS m/z 334.1 (M++1).
