Procedure

An ethanolic suspension (20 mL) of 3-[8-chloro-1-(2-phenylquinolin-7-yl)imidazo[1,5-a]pyrazin-3-yl]cyclobutanone: (2.5 mmol) was charged with NaBH4(2.5 mmol) at rt. The reaction mixture was stirred at rt for 30 min until the reaction solution turned clear. The reaction mixture was quenched by an addition of Na2SO4.10 H2O and concentrated under reduced pressure. The crude mixture was dissolved in DCM, washed with water (3×15 mL), dried over Na2SO4, filtered and concentrated in vacuo to afford the title compound as a yellow solid. 1H NMR (400 MHz, CDCl3) δ 8.52 (s, 1H), 8.28 (d, J=8.0 Hz, 1H), 8.19 (d, J=8.0 Hz, 2H), 7.93-7.87 (m, 3H), 7.58-7.52 (m, 3H), 7.47-7.45 (m, 1H), 7.37 (d, J=5.2 Hz, 1H), 4.44 (b, 1H), 3.37 (p, J=8.0 Hz, 1H), 3.03-2.96 (m, 2H), 2.60-2.53 (m, 2H); MS (ES+): m/z 427 (100) [MH+].
