실험 절차

5-Amino-3-methylisoquinoline (390 mg, 2.47 mmol) and the product from Example 194A (0.36 mL, 2.45 mmol) were heated in toluene (10 mL) at 80° for 2.5 hours. Upon cooling to room temperature, a precipitate formed, which was collected by filtration, washed with toluene, and air-dried. Remaining impurities were removed by slurrying the solid in 9:1 CH2Cl2:CH3OH and then filtering the mixture to provide the title compound. The corresponding hydrochloride salt was formed by treatment of the free base with methanolic HCl. 1H NMR (300 MHz, DMSO-d6) δ 9.17 (s, 1H), 8.27 (s, 1H), 8.17 (dd, 1H, J=7.8 Hz, 1.0 Hz), 7.74 (s, 1H), 7.71 (d, 1H, J=8.1 Hz), 7.61 (m, 2H), 7.50 (t, 1H, J=8.0 Hz), 7.35 (dd, 1H, J=8.3 Hz, 2.2 Hz), 7.12 (t, 1H, 5.9 Hz), 4.37 (d, 2H, J=6.1 Hz), 2.65 (s, 3H); MS (ESI+) m/z 360/362 (M+H, 35Cl/37Cl).
