実験手順
[(1S)-1-carbamoyl-5-(2,2,2-trichloroethoxycarbonylamino)pentyl]carbamic acid tert butyl ester (39.5 g; 94 mmole) was dissolved in a solution of hydrogen chloride in ethyl acetate (1.5 M, 300 ml) and stirred for 30 min. Diethyl ether (300 ml) was added and the precipitate was filtered and dried to afford 30.5 g of ((5S)-5-amino-5-carbamoylpentyl)carbamic acid 2,2,2-trichloroethyl ester hydrochloride.
