To a solution of 5-bromo-3-chloro-1-methoxyisoquinoline (420 mg, 1.54 mmol) in DMSO (4.0 mL) was added NaOMe (0.5 M in MeOH, 4.0 mL, 2.0 mmol). The solution was heated at 90° C. for 1.5 hours in a microwave reactor. The mixture was poured into water then extracted with EtOAc. The organics were dried over Na2SO4, filtered, and concentrated. The residue was purified by silica gel chromatography eluting with 15% EtOAc/hexanes to afford the title compound: 1H NMR (500 MHz, CDCl3): δ 8.15 (d, J=8.5 Hz, 1H), 7.87 (d, J=8.0 Hz, 1H); 7.18 (t, J=8.0 Hz, 1H), 6.85 (s, 11-1), 4.18 (s, 3H), 4.05 (s, 3H). LC6: 3.67 min, (M+H): 268.
