Procedure

A round bottom flask was charged with N-(4-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)bicyclo[2.2.2]octan-1-yl)cyclopropanesulfonamide (0.27 g, 0.50 mmol), aqueous NaOH (1N, 1.0 mL, 1.0 mmol), and 1,4-dioxane (8 mL). The reaction mixture was stirred at about 60° C. for about 2 h. NH4OAc (50 mM aqueous buffer, 2 mL) and DMF (7 mL) were added and insoluble material was removed via filtration. The filtrate was purified by RP-HPLC (Table 2, Method c). The appropriate fractions were combined, the organic solvent was concentrated under reduced pressure, the resulting solid was collected by filtration, washed with water (20 mL), and lyopholized to give N-(4-(6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)bicyclo[2.2.2]octan-1-yl)cyclopropanesulfonamide as a solid (0.11 g, 56%): LC/MS (Table 2, Method a) Rt=1.53 min; MS m/z 387 (M+H)+.
