1.25 M hydrochloric acid solution (9.76 mL, 12.2 mmol) dissolved in methanol was added dropwise to the tert-butyl 6-carbamoyl-3-azabicyclo[3.1.0]hexane-3-carboxylate (177 mg, 0.784 mmol) prepared in Example 4 and stirred for 3 hours. The completion of the reaction was confirmed by TLC (CH2Cl2:MeOH=15:1). After the reaction was completed, the reaction mixture was concentrated under reduced pressure to obtain 127 mg (100%) of the target compound.
