Versuchsvorschrift
To 1-(4-((trans)-4-(1-bromo-8-methylimidazo[1,5-a]pyrazin-3-yl)cyclohexyl)piperazin-1-yl)ethanone (0.108 mmol, 45.4 mg) in ethanol was added 2 M hydrochloric acid (4.32 mmol, 2.16 ml) and stirred at reflux for four hours. The reaction mixture was cooled, concentrated in vacuo, coevaporated with toluene twice and washed with dichloromethane twice to give 1-bromo-8-methyl-3-((trans)-4-(piperazin-1-yl)cyclohexyl)imidazo[1,5-a]pyrazine hydrochloride (56 mg) product which was used without further purification.
