実験手順
403 mg of {3-[4-(aminoiminomethyl)benzyl]-2,5-dioxopyrrolidin-1-yl}acetic acid hydrochloride are coupled with 270 mg of D,L-homophenylalanine methyl ester by the process described above. After working up and chromatographic purification, 343 mg of {3-[4-(aminoiminomethyl)benzyl]-2,5-dioxopyrrolidin-1-yl}-acetyl-D,L-homophenylalanine methyl ester are obtained.
後処理
