실험 절차

A solution of [4-amino-1-(2-fluoro-2-methylpropyl)-1H-imidazo[4,5-c][1,5]naphthyridin-2-yl]methyl acetate (1.13 g, 3.41 mmol) dissolved in 10 mL of methanol was treated with 10 mL of a 7% solution of ammonia in methanol. The mixture was stirred for 2 hours and then concentrated under reduced pressure. The resulting solid was treated with H2O and the mixture was heated to reflux for 15 minutes. The mixture was cooled and the resulting light-yellow solid was isolated by filtration. The light-yellow, solid was then treated with 20 mL of CH2Cl2 and the mixture was stirred rapidly for several minutes. The mixture was filtered and the resulting white solid was washed with several portions of cold CH2Cl2 and dried with suction. Crystallization from ethanol/H2O gave 477 mg of [4-amino-1-(2-fluoro-2-methylpropyl)-1H-imidazo[4,5-c][1,5]naphthyridin-2-yl]methanol as fluffy cream colored crystals, mp 240-241° C. 1H NMR (300 MHz, DMSO-d6) δ 8.50 (dd, J=1.5, 4.3 Hz, 1H), 7.93 (dd, J=1.5, 8.4 Hz, 1H), 7.46 (dd, J=4.3, 8.4 Hz, 1H), 6.92 (s, 2H), 5.62 (t, J=5.8 Hz, 1H), 5.33 (br s, 2H), 4.83 (d, J=4.7 Hz, 2H), 1.33 (d, J=20.3 Hz, 6H); 13C NMR (125 MHz, DMSO-d6) δ 154.3, 152.7, 143.1, 140.8, 134.2, 133.4, 133.2, 128.7, 122.5, 96.8 (d, J=170 Hz), 56.7 (d, J=9.5 Hz), 52.7 (d, J=21.4 Hz), 24.5; MS (ESI) m/z 290 (+H)+; Anal. calcd for C14H16FN5O: C, 58.12; H, 5.57; N, 24.21.
