반응 단계

162 mg (0.5 mmol) of {[2-(tert-butoxycarbonylamino)-ethyl]-methyl-amino}-acetic acid benzyl ester prepared in Process 3-A was dissolved in methanol (5 mL), and then 5% palladium-carbon was added to it, and this was stirred under a hydrogen atmosphere at room temperature for one hour. After filtering off the insoluble material, the filtrate was concentrated to yield 116 mg (100%) of {[2-(tert-butoxycarbonylamino)-ethyl]-methyl-amino}-acetic acid as a colorless viscous oil.
