Versuchsvorschrift

Diethyl 3-[[4-[[4-(aminoiminomethyl)phenyl]amino]-1,4-dioxobutyl]amino]hexanedioate (700 mg) prepared in Example 19, Step 2 was added to water/acetonitrile (20 ml) followed by lithium hydroxide (150 mg) at 25° C. The mixture was stirred for 30 min. The course of the reaction was monitored by RPHPLC. After satisfactory product was formed the reaction was neutralized with TFA and purified by reverse phase chromatography (0.05% TFA water/acetonitrile) to result in 350 mg of a white solid: H NMR (d6 -DMSO) δ1.55 (m, 1H), 1.7 (m, 1H), 2.3 (m, 2H), 2.57 (m, 2H), 2.67 (m, 2H), 4.03 (m, 1H), 7.79 (s, 4H), 7.99 (d, 1H, J=8 Hz), 8.86 (bs, 2H), 9.17 (bs, 2H), 10.2 (s, 1H); MS (FAB) m/z 379.2 (MH+).
