Procedure

A 1 M aqueous NaOH solution was added to a mixture of methyl 4-{4-[5-(3-{[(carbamimidoylcarbamoyl)amino]methyl}phenyl)pyrimidin-2-yl]piperazin-1-yl}-3-chlorobenzoate (208 mg), THF (2 ml), and EtOH (2 ml), followed by stirring at room temperature for 2 hours. The reaction mixture was neutralized with 1 M hydrochloric acid, and the precipitated solid was collected by filtration. A 4 M hydrogen chloride/dioxane solution (1 ml) was added to a mixture of the obtained solid and dioxane (3 ml), followed by stirring at room temperature overnight. The insoluble matter was collected by filtration to obtain 4-{4-[5-(3-{[(carbamimidoylcarbamoyl)amino]methyl}phenyl)pyrimidin-2-yl]piperazin-1-yl}-3-chlorobenzoic acid dihydrochloride (112 mg).
