To a mixture of methyl (1S,2R)-2-[(tert-butoxycarbonyl)amino]cyclopentanecarboxylate (0.84 g) and ethyl acetate (2.5 ml) was added a 4 M hydrogen chloride/ethyl acetate solution (5.0 ml) under ice-cooling, followed by stirring at room temperature for 2.5 hours. The reaction mixture was concentrated under reduced pressure to obtain methyl (1S,2R)-2-aminocyclopentanecarboxylate hydrochloride (0.72 g).
