実験手順

1-(2-Phenyl-quinolin-7-yl)-3-piperidin-4-yl-imidazo[1,5-a]pyrazin-8-ylamine-tris HCl salt (59.0 mg, 0.1 mmol) was dissolved in triethylamine (1.0 mL) and DMF (0.5 mL). Acetic anhydride (12.0 μL, 0.1 mmol) was added and the reaction was stirred for 1 h. The reaction was concentrated in vacuo and purified by silica gel chromatography (Jones Flashmaster, 2 g/12 mL cartridge, eluting with 2% 7N NH3 in methanol/CH2Cl2). The sample was further purified using MDPS to yield 1-{4-[8-amino-1-(2-phenylquinolin-7-yl)imidazo[1,5-a]pyrazin-3-yl]piperidin-1-yl}ethanone as a pale yellow solid; 1H NMR (CDCl3, 400 MHz) δ 1.95 (ddd, 1H, J=22.4, 11.2, 4.0 Hz), 2.03-2.23 (m, 6H), 2.90 (ddd, 1H, J=13.6, 13.6, 2.8 Hz), 3.19-3.32 (m, 2H), 4.01 (bd, 1H, J=13.6 Hz), 4.64 (bd, 1H, J=13.2 Hz), 5.44 (bs, 2H), 7.11 (d, 1H, J=4.8 Hz), 7.24 (d, 1H, J=5.6 Hz), 7.46 (ddd, 1H, J=6.0, 2.4, 0.8 Hz), 7.50-7.54 (m, 2H), 7.86-7.94 (m, 3H), 8.16 (ddd, 2H, J=7.2, 3.6, 1.6 Hz), 8.24 (d, 1H, J=8.4 Hz), 8.38 (s, 1H); MS (ES+): m/z 463 (10) [MH+]; HPLC: tR=2.1 min (OpenLynx, polar—5 min).
