실험 절차
To a 1 dram vial with septa screw cap was added (1-cyclobutyl-1H-imidazol-4-yl)-carbamic acid phenyl ester (Example 4, 50 mg, 0.19 mmol), 5-aminoisoquinoline (30 mg, 0.21 mmol), and 1:1 dioxane-DMF (1 mL). The reaction mixture was heated at 70° C. for 2 h. The reaction mixture was adsorbed onto silica gel and was purified by silica gel chromatography (40:1 chloroform-methanol) to afford 30 mg (52% yield) of 1-(1-cyclobutyl-1H-imidazol-4-yl)-3-isoquinolin-5-yl-urea; 1H NMR (400 MHz, CD3OD) δ9.21 (d, J=1.7 Hz, 1H), 8.45 (d, J=6.2 Hz, 1H), 8.24 (d, J=7.5 Hz, 1H), 7.98 (d, J=5.4 Hz, 1H), 7.84 (dd, J=2.3, 8.3 Hz, 1H), 7.66 (m, 1H), 7.54 (s, 1H), 7.12 (brs, 1H), 4.66 (m, 1H), 2.5-2.3 (m, 4H), 1.9 (m, 2H); MS (AP/Cl): 308.0 (M+H)+.
