実験手順
A solution of [4-(tert-butoxycarbonylamino-methyl)-phenyl]-carbamic acid benzyl ester (1.25 g, 3.51 mmol) in EtOAc (20 mL) was cooled on an ice-bath and 4 M hydrogen chloride in EtOAc (20 mL) was added. The mixture was stirred at ambient temperature for 20 min. The precipitate was collected by filtration, washed with EtOAc, and dried under reduced pressure to give (4-aminomethyl-phenyl)-carbamic acid benzyl ester hydrochloride (957 mg, 93%) as a white solid.
