Reaction Steps

Benzyl 4-(8-methylimidazo[1,5-a]pyrazin-3-yl)piperazine-1-carboxylate (486 mg) in 37% hydrochloric acid (97 mmol, 8 ml) was stirred at room temperature for two hours. Then water (16 ml) was added and the mixture washed twice with diethyl ether. The aqueous layer was concentrated in vacuo and co-evaporated with toluene and ethanol to give 8-methyl-3-(piperazin-1-yl)imidazo[1,5-a]pyrazine hydrochloride (322 mg).
