Procedure

8-Bromo-5-isoquinolinamine (120 mg, 0.52 mmol) in THF:toluene (5 mL, 1:4) was treated with 2,4-dichloro-1-(isocyanatomethyl)benzene (108 mg, 0.52 mmol) in THF (0.5 mL). After stirring for 16 hours at room temperature, the mixture was filtered and the filter cake was dried under reduced pressure to provide the title compound. MS (ESI+) m/z 426 (M+H)+; MS (ESI−) m/z 424 (M−H)−; 1H NMR (DMSO, 300 MHz) δ 4.42 (d, 5.8, 2H), 7.22 (t, J 5.8, 1H), 7.65 (m, 1H), 7.91 (d, J 8.5, 1H), 8.02 (d, J 6.1, 1H), 8.22 (d, J 8.5, 1H), 8.69 (d, J 5.8, 1H), 9.01 (s, 1H), 9.44 (s, 1H); Anal. Calcd for C17H12BrCl2N3O.HCl+0.25EtOH: C, 44.41; H, 3.14; N, 8.88. Found: C, 44.80; H, 2.76; N, 8.84.
