Versuchsvorschrift

60% sodium hydride (13 mg) and 1-cyclopentyl-4-hydroxypiperidine (60 mg) were added to a DMF solution (3 ml) of 2-fluoro-5-[4-cyanophenyl]pyridine (56 mg), and stirred at 130° C. for 7 hours. The reaction mixture was cooled to room temperature, and water was added thereto and extracted with ethyl acetate. The organic layer was washed with saturated saline solution, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified through silica gel column chromatography (C-300, chloroform:methanol=9:1) to obtain the entitled compound.
