Versuchsvorschrift

To a solution of tert-butyl 3-(6H-imidazo[1,5-a]pyrrolo[2,3-e]pyrazin-1-yl)-4-methylpiperidine-1-carboxylate (12.2 g, 34.3 mmol) in 1,4-dioxane (100 mL) was added 4N HCl (4N in 1,4-dioxane, 25.7 mL, 103 mmol). The reaction mixture was heated at about 60° C. for about 2 h. The mixture was allowed to cool to ambient temperature and was diluted with Et2O (100 mL). The mixture was triturated and filtered, and the precipitate was washed with Et2O (100 mL) to give 1-(4-methylpiperidin-3-yl)-6H-imidazo[1,5-a]pyrrolo[2,3-e]pyrazine hydrochloride (10 g, 98% yield) as a tan solid: LC/MS (Table 2, Method a) Rt=1.05 min; MS m/z: 256 (M+H)+.
