Reaction Steps

A solution of m-chloroperbenzoic acid (0.013 g, 0.000075 mol) in DCM (0.4 g, 0.005 mol) was added slowly to a solution of 1-(8-fluoro-2-phenyl-quinolin-7-yl)-3-methylsulfanyl-imidazo[1,5-a]pyrazin-8-ylamine (30 mg, 0.000075 mol) in DCM (2 mL, 0.04 mol) at −78° C. The reaction mixture was allowed to stir at that temp for 30 min. The reaction mixture was transferred to an ice-bath and stirred for 1 h. 50% consumption of SM was observed. The reaction mixture was stirred in ice-bath for 1 h. An additional 0.5 eq of m-chloroperbenzoic acid was added to the reaction mixture and the reaction mixture was warmed to rt and stirred for 2 h. The reaction mixture was concentrated in vacuo. Purification by prep TLC (7% MeOH in DCM) afforded the title compound as a light yellow solid. 1H NMR (400 MHz, CDCl3): δ=5.13 (br. s., 2H), 7.32 (d, J=5.05 Hz, 1H), 7.48-7.60 (m, 3H), 7.69 (dd, J=8.46, 6.44 Hz, 1H), 7.76-7.81 (m, 1H), 8.06 (d, J=8.84 Hz, 1H), 8.15 (d, J=5.05 Hz, 1H), 8.25 (dd, J=8.21, 1.39 Hz, 2H), 8.32 (dd, J=8.72, 1.39 Hz, 1H). MS (ES+): m/z 417.95 (100)[MH+]. HPLC: tR=2.63 min (Open Lynx polar—5 min).
