title compound

(S)-2-(3-{(4-carbamimidoylphenylamino)-[2-fluoro-4-(2-hydroxyethoxy)-5-methoxyphenyl]methyl}-5-oxo-4,5-dihydro-[1,2,4]triazol-1-yl)benzoic acid

Reaktionsbedingungen

Vorschrift

The same procedure was carried out as in Examples (3f)-(3h), except that (2-{4-[2-(t-butyldimethylsilanyloxy)ethoxy]-2-fluoro-5-methoxyphenyl}-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene)carbamic acid methyl ester and 2-hydrazinobenzoic acid hydrochloride were used instead of respectively the {2-[2-fluoro-3-(2-fluoroethoxy)-5-methoxyphenyl]-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene}carbamic acid methyl ester in Example (3f) and 2-hydrazinopyrimidine in Example (3f), to give the title compound as a white solid.
