Reaction Steps

To 1-(4-(4-(8-methylimidazo[1,5-a]pyrazin-3-yl)piperazin-1-yl)piperidin-1-yl)ethanone (0.102 mmol, 35 mg) in dichloromethane (1 ml) at room temperature was added N-bromosuccinimide (0.102 mmol, 18.19 mg). After stirring at room temperature for 5 minutes water was added and the mixture extracted three times with dichloromethane. The combined organic extracts were dried over a phase separation filter and concentrated in vacuo to give 1-(4-(4-(1-bromo-8-methylimidazo[1,5-a]pyrazin-3-yl)piperazin-1-yl)piperidin-1-yl)ethanone (32 mg).
