الإجراء التجريبي

Prepared analogously to Example 90 from 1-methyl-2-[N-(4-amidinophenyl)aminomethyl]benzimidazol-5-yl-carboxylic acid-N-(2-pyridyl)-N-(2-methoxycarbonylethyl)amide hydrochloride and n-butyl chloroformate. Yield: 30% of theory, C31H35N7O5 (585.7); Rf value: 0.62 (silica gel; dichloromethane/methanol=9:1); EKA mass spectrum: (M+H)+=586; (M+H+Na)++=304.7; (M+2H)++=293.7.
