(1-Chloro-isoquinolin-5-yl)-carbamic acid phenyl ester (150 mgs, 0.5 mmol), and 4-trifluoromethyl-benzylamine (88 mgs, 0.5 mmol) were combined and stirred overnight in DMSO (4 mL) at ambient temperature. The product was purified by directly injecting the crude reaction onto a reverse phase prep-HPLC (90–10% water:acetonitrile gradient). The appropriate fractions were lyophilized to yield 1-(1-Chloro-isoquinolin-5-yl)-3-(4-trifluoromethyl-benzyl)-urea (118 mgs, 61%) MS (MH+) 379.9; 1H NMR (DMSO-d6) δ 4.47 (d, 2H, J=5.8 Hz), 7.21 (m, 1H), 7.56 (d, 2H, J=8.1 Hz), 7.71–7.76 (m, 3H), 7.93 (d, 1H, J=8.5), 8.01 (d, 1H, J=6.0 Hz), 8.34–8.36 (m, 2H), 8.95 (s, 1H). HPLC Rt=4.57 min (90–10% water:acetonitrile gradient, 100% pure).
