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. 1HNMR (300 MHz, DMSO-d6) 69.17 (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).
