To a solution of 1-cyclohexyl-6-tosyl-6H-imidazo[1,5-a]pyrrolo[2,3-e]pyrazine (0.020 g, 0.051 mmol) in 1,4-dioxane (3 mL) was added aqueous NaOH (2 N, 0.380 mL, 0.760 mmol). The reaction mixture was heated to about 90° C. After about 5 h, the reaction mixture was cooled to ambient temperature and diluted with EtOAc (10 mL) and saturated aqueous NH4Cl (10 mL). The organic layer was separated and washed with water (10 mL) followed by brine (10 mL), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure to provide 1-cyclohexyl-6H-imidazo[1,5-a]pyrrolo[2,3-e]pyrazine as a tan solid (0.011 g, 90%): LC/MS (Table 2, Method a) Rt=1.92 min; MS m/z: 241 (M+H)+.
