Procedure

The title compound was prepared using 5-aminoisoquinoline, the product of Example 76B and the procedure described in Example 73B except that THF was used as solvent. The product was recrystallized from ethyl acetate to provide the title compound as a white solid (840 mg, 34%). MS (ESI+) m/z 355 (M+H)+; MS (ESI−) m/z 353 (M−H)−; 1H NMR (DMSO-d6, 300 MHz) δ 1.63 (s, 6H), 7.23 (s, 1H), 7.37 (d, J 8.8, 2H), 7.47 (d, J 8.8, 2H), 7.73 (t, J 9.2, 1H), 7.93 (d, J 8.1, 1H), 8.25 (d, J 6.4, 1H), 8.39 (d, J 8.1, 1H), 8.67 (d, J 6.4, 1H), 8.87 (s, 1H), 9.58 (s, 1H); Anal. Calcd for C19H18ClN3O HCl 0.25EtOH: C, 60.40; H, 5.33; N, 10.54. Found: C, 60.82; H, 5.23; N, 10.45.
