実験手順
A solution of 1-(3-benzyloxy-phenyl)-8-chloro-2H-imidazo[1,5-a]pyrazin-3-one (50.0 mg, 0.14 mmol) and silver carbonate (85 mg, 0.31 mmol) in anhydrous EtOH (1 mL) was charged with iodoethane (0.012 mL, 0.15 mmol) and stirred at rt for 48 h. The reaction mixture was partitioned between DCM and H2O and separated. The aqueous layer was washed with DCM (3×) and the combined organic layers were washed with brine (1×), dried over Na2SO4, filtered and concentrated in vacuo and the crude material was purified by chromatography on silica gel [eluting with 2% EtOAc in DCM], to yield the desired product as a yellow oil/gum; 1H NMR (CDCl3, 400 MHz) δ 1.51 (t, J=7.2 Hz, 3H), 4.68 (q, J=7.2 Hz, 2H), 5.13 (s, 2H), 7.00-7.05 (m, 1H), 7.13 (d, J=5.2 Hz, 1H), 7.27-7.48 (m, 9H); MS (ES+) m/z=380.07 (100) [MH+], HPLC: tR=4.04 min (MicromassZQ, polar—5 min).
