Sodium hydride (17 mg, 60%) was added slowly to an ice-cooled solution of 1-(2,4-difluoro-phenyl)-3-(5-methyl-1H-pyrazol-3-ylamino)-isoquinolin-6-ol (150 mg) in 2 mL N,N-dimethylformamide (DMF). After stirred for 30 min, 1-Bromo-2-methoxy-ethane (59 mg) in 1 mL DMF was added cautiously by syringe. The mixture was warmed to room temperature and stirred overnight, then diluted with 1 mL methanol and directly sent to prep-HPLC. The product [1-(2,4-difluoro-phenyl)-6-(2-methoxy-ethoxy)-isoquinolin-3-yl]-(5-methyl-1H-pyrazol-3-yl)-amine (40 mg) was obtained as a yellow solid. LC-MS m/e 411(MH+). 1H NMR (400 MHz, DMSO) 9.12(s, 1H), 7.81(s, 1H), 7.61(m, 1H), 7.43(t, 1H), 7.34(d, 1H), 7.25(t, 1H), 7.10(d, 1H), 6.85(d, 1H), 5.81(s, 1H), 4.23(m, 2H), 3.71(m, 2H), 3.32(s, 3H), 2.20(s, 3H).
