Reaction Steps

Benzyl 4-(1-bromo-8-methylimidazo[1,5-a]pyrazin-3-yl)piperidine-1-carboxylate (0.471 mmol, 202 mg) was dissolved in 37% hydrochloric acid (32.9 mmol, 2.745 ml). The reaction mixture was stirred at room temperature for one hour. Water was added and the aqueous mixture washed twice with diethyl ether. The aqueous layer was basified with aqueous sodium hydroxide and extracted twice with dichloromethane. The combined organic extracts were dried (sodium sulfate) and concentrated in vacuo to give 1-bromo-8-methyl-3-(piperidin-4-yl)imidazo[1,5-a]pyrazine (100 mg).
