Procedure
To a mixture of tert-butyl (3-((3-chloropyrazin-2-yl)oxy)cyclobutyl)carbamate (2.8 g, 9.61 mmol) in MeOH (20 mL) was added HCl/MeOH (20 mL, saturated with HCl gas), and then stirred at RT for 1 hour. The reaction mixture was concentrated to give 3-((3-chloropyrazin-2-yl)oxy)cyclobutanamine hydrochloride (2.2 g, 9.61 mmol, 100%). ESI-MS (M+1): 200 calc. for C8H10ClN3O 199.
