실험 절차
To a solution of N-[(R)-(1-benzyloxycarbonyl-3-piperidyl)carbonyl]-2(S)-(tert-butoxycarbonylamino)-β-alanine ethyl ester (0.4 g) in ethyl acetate (4 ml) was added 4N HCl in ethyl acetate (2.1 ml) under stirring at 0° C. After stirring at ambient temperature for 2 hours, the resulting precipitates were collected by filtration to give N-[(R)-1-benzyloxycarbonyl-3-piperidyl)carbonyl]-2(S)-amino-β-alanine ethyl ester hydrochloride (0.31 g).
