Versuchsvorschrift

To a dimethylsulfoxide (200 mL) solution of 18.7 g of 4-{3-[4-(3-hydroxypropyl)-1-piperidinyl]propoxy}benzonitrile was added 8.92 mL of a 50% hydroxylamine aqueous solution at room temperature, which was then stirred at the same temperature for 5 hours and 30 minutes. Thereto was added 8.92 mL of a 50% hydroxylamine aqueous solution at room temperature, which was stirred at the same temperature for 15 hours and 50 minutes. To the reaction mixture were added 2-propanol and water, which was then stirred at room temperature for one hour. The precipitate was collected by filtration and washed with water to provide 17.5 g of N′-hydroxy-4-{3-[4-(3-hydroxypropyl)-1-piperidinyl]propoxy}benzamidine as white solid form.
