실험 절차

A solution of 3-(8-chloro-1-iodo-imidazo[1,5-a]pyrazin-3-yl)-1-hydroxymethyl-cyclobutanol (4.08 g, 0.011 mol) in THF (120 mL) and water (40 mL) was charged with sodium periodate (2.8 g, 0.013 mol) at 0° C. The reaction warmed to rt and stirred for 5 h. The reaction mixture was diluted with ethyl acetate and then washed with brine. The organic phase was dried over Na2SO4, filtered, and concentrated in vacuo to afford the title compound as a yellow solid; 1H NMR (CDCl3, 400 MHz) δ 7.56 (1H, d, J=4.94), 7.32 (1H, d, J=4.98), 3.64 (5H, m); MS (ES+): m/z 347.82/349.85 (100/30) [MH+]; HPLC: tR=2.89 min. (OpenLynx, polar—5 min.).
