실험 절차

4-[[4-(Aminoiminomethyl)phenyl]amino]-4-oxobutanoic acid hydrochloride was added to dry DMF (35 ml) followed by N-methylmorpholine (0.39 g, 1 eq.) and isobutyl chloroformate (0.53 g, 3.9 mmol) at 25° C. The mixture was stirred for 5 min. (S)-ethyl 3-amino-4-pentynoate was added followed by diisopropylethylamine and a catalytic amount of dimethylaminopyridine. After 1 hour, the solvent was removed under reduced pressure and the product was purified by reverse phase chromatography to give (3S)-ethyl 3-[[4-[[4-(aminoiminomethyl)phenyl]amino]-1,4-dioxobutyl]amino]-4-pentynoate.
