Procedure

1-[2-Fluoro-3-(hydroxymethyl)phenyl]-4-(pyridin-3-yl)piperidin-4-ol (187 mg), DMF (5.5 ml), and CDI (201 mg) were mixed, followed by stirring at room temperature for 2 hours. Guanidine carbonate (279 mg) was added to the reaction mixture, followed by stirring at room temperature overnight. Water was added to the reaction mixture, followed by ice-cooling and stirring for 30 minutes, and the generated solid was collected by filtration, washed with water, and then dried at 50° C. under reduced pressure. The obtained solid was purified by silica gel column chromatography (CHCl3/MeOH) to obtain 2-fluoro-3-[4-hydroxy-4-(pyridin-3-yl)piperidin-1-yl]benzyl carbamimidoylcarbamate (160 mg).
