Procedure

To a solution of N-(4-(6-tosyl-6H-imidazo[1,5-a]pyrrolo[2,3-e]pyrazin-1-yl)bicyclo[2.2.2]octan-1-yl)cyclopropanesulfonamide (0.025 g, 0.046 mmol) in 1,4-dioxane (3 mL) was added aqueous NaOH (2 N, 0.35 mL, 0.70 mmol). The reaction mixture was heated to about 90° C. After about 6 h, the reaction mixture was cooled to ambient temperature and EtOAc (3 mL) and saturated aqueous NH4Cl (1.5 mL) was added. The layers were separated and the organic layer was washed with water (1.5 mL) followed by brine (1.5 mL), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure to provide N-(4-(6H-imidazo[1,5-a]pyrrolo[2,3-e]pyrazin-1-yl)bicyclo[2.2.2]octan-1-yl)cyclopropanesulfonamide as a tan solid (0.012 g, 67%). LC/MS (Table 2, Method a) Rt=1.65 min; MS m/z: 386 (M+H)+.
