Reaction Steps

20 M of NH3 in H2O(10 mL) was added to a suspension of 1,3-Dibromo-8-chloro-imidazo[1,5-a]pyrazine (1.726 g, 0.007425 mol) in 2-Butanol (7.49 mL, 0.0817 mol). The mixture was heated in an oil bath set at 90° C. overnight. The reaction mixture was concentrated in vacuo and purified by flash column chromatography using 1→6% MeOH in DCM to obtain the title compound as a yellow solid. MS (ES+): m/z 294.83 (85) [MH+]. HPLC: tR=1.58 min (Open Lynx polar—5 min). 1H NMR (400 MHz, CD3OD):δ=7.10 (d, J=5.05 Hz, 1H), 7.43 (d, J=5.05 Hz, 1H)
