Reaction Steps

To 1-(4-(8-methylimidazo[1,5-a]pyrazin-3-yl)piperazin-1-yl)ethanone (0.208 mmol, 54 mg) in dichloromethane (1 ml) at room temperature was added N-bromosuccinimide (0.208 mmol, 37.1 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-(1-bromo-8-methylimidazo[1,5-a]pyrazin-3-yl)piperazin-1-yl)ethanone (62 mg).
