Participants

Reaction Steps

(±)-3-[[5-[4-(Aminoiminomethyl)phenyl]-1oxopentyl]amino]-5-(methylthio)pentanoic acid (2.5 g) was added to water (15 ml) and acetic acid (5 ml) and 30% H2O2 (10 ml) . The oxidation was allowed to proceed for 48 hours after which the reaction mixture was purified by reverse phase chromatography (water/acetonitrile) and lyophilized to give 1.6 g of the title compound as a white solid: 1H NMR (d6 -DMSO) δ1.51 (m, 4H), 1.56 (m, 2H), 2.0 (m, 2H), 2.10 (s, 3H), 2.90 (m, 4H), 2.71 (m, 2H), 4.10 (m, 1H), 7.35 (m, 9H), 7.7 (bd, 1H, J=7.9 Hz), 9.10 (bs, 2H), 9.25 (bs, 2H); MS (FAB) m/e 398.2 (M+H+).
