Ethyl β-[[3-[4-(aminoiminomethyl)benzyl]aminopropanoyl]amino]3-pyridine-propanoate (70 mg) was treated with 1N lithium hydroxide and methanol (1:1; 20 ml) for 5 min. Methanol was removed under reduced pressure and the residue was purified by HPLC using acetonitrile/water/trifluoroacetic acid system. The desired fractions were collected and lyophilized to give 50 mg of white material (77% yield). FAB-MS: MH+ =370.3.
