Vorschrift
A solution of 4-(2-amidino-8-chloronaphthalen-7-yloxymethyl)-1-(pyridin-4-yl)piperidine-4-carboxylic acid ethyl ester dihydrochloride (78 mg) in conc. hydrochloric acid was stirred at 50° C.-100° C. for 3 hours. After completion of the reaction, the solvent was evaporated and the obtained residue was separated by HPLC (0.05% aqueous trifluoroacetic acid:methanol=1:1). The obtained residue was treated with hydrogen chloride-ethanol and dried under reduced pressure to give the title compound (49 mg).
