To a solution of (4E)-6-bromo-4-(methoxymethylene)isoquinoline-1,3(2H,4H)-dione (0.2 g, 0.71 mmol) in N,N′-dimethylformamide is added 3-(aminomethyl)pyridine (0.073 mL, 0.71 mmol). The reaction mixture is heated at 60° C. under N2. After reaction is completed, diethyl ether is added, and the red precipitate is isolated and washed with methanol, ether, and hexane respectively to afford 0.16 g (63.2% yield) of orange solid: mp 299-300° C.; 1H NMR (DMSO-d6) δ 11.09 (s, 1H), 10.69 (m, 1H), 8.74 (d, J=9 Hz, 1H), 8.63 (s, 1H), 8.52 (d, J=3 Hz, 1H), 8.10 (s, 1H), 7.84 (m, 2H), 7.42 (m, 1H), 7.31 (d, J=9 Hz, 1H), 3.40 (d, J=4.8 Hz, 2H); MS (ESI) m/z 355.7 and 357.7 (M−H)−1, Analysis for C16H12BrN3O2, Calcd: C, 53.70; H, 3.38; N, 11.70. Found: C, 53.45; H, 3.23; N, 11.74.
