実験手順

0.45 g (0.84 mMol) of 2-[N-(4-amidinophenyl)-aminomethyl]-benzothiazole-5-carboxylic acid-N-phenyl-N-(2-ethoxycarbonylethyl)-amide were dissolved in 15 ml of ethanol, mixed with 2 ml of 2N sodium hydroxide solution and stirred for 4 hours at room temperature. Then the mixture was acidified with 3 ml of 2N hydrochloric acid and the solvent was distilled off. The crude product obtained was taken up in 5 ml dichloromethane/ethanol (2:1) and filtered to remove the insoluble sodium chloride. After the distillation of the solvent the desired compound was obtained as a yellow foam. Yield: 0.26 g (67% of theory), Rf value: 0.47 (silica gel; methanol/5% aqueous sodium chloride=6:4) C25H23N5O3S (473.55) Mass spectrum: (M+H)+ =474
