実験手順
A solution of (2S,4R)-2-[(Z)-5-carboxy-1-pentenyl]-4-(4-chlorophenylsulfonylamino)-1-(3-pyridylmethyl)pyrrolidine (104 mg) in ethyl acetate (5 ml) was added 1N-hydrogen chloride in ethyl acetate (0.25 ml) and the precipitated brown solid was collected and dried in vacuo to give (2S,4R)-2-[(Z)-5-carboxy-1-pentenyl]-4-(4-chlorophenylsulfonylamino)-1-(3-pyridylmethyl)pyrrolidine hydrochloride (100 mg) as a brown powder.
