Reaction Steps

A 1 M aqueous NaOH solution (1.14 ml) was added to a mixture of 5-[4-(3-{[(carbamimidoylcarbamoyl)oxy]methyl}-2-fluorophenyl)piperazin-1-yl]pyridine-2-carboxylate methyl ester (326 mg), THF (9 ml), and MeOH (3 ml), followed by stirring at room temperature overnight. 1 M hydrochloric acid (1.14 ml) was added to the reaction mixture, followed by stirring at room temperature for 1 hour. The generated solid was collected by filtration, washed with water, and then dried at 50° C. under reduced pressure to obtain 5-[4-(3-{[(carbamimidoylcarbamoyl)oxy]methyl}-2-fluorophenyl)piperazin-1-yl]pyridine-2-carboxylic acid (293 mg).
