Procedure

tert-Butyl 3-{[6-(hydroxymethyl)pyridin-3-yl]oxy}azetidine-1-carboxylate (198 mg) was mixed with THF (3 ml), and sodium hydride (55% suspended in oil) (50 mg) was added thereto at 0° C., followed by stirring at 0° C. for 30 minutes. Methyl iodide (0.4 ml) was added to the reaction mixture, followed by stirring at room temperature for 3 hours. EtOAc and water were added to the reaction mixture, and the organic layer was dried over Na2SO4, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (CHCl3/MeOH). The purified product thus obtained was mixed with DCE (2.8 ml), and TFA (902 mg) was added thereto, followed by stirring at room temperature for 5 hours. CHCl3 and a 1 M aqueous NaOH solution were added to the reaction mixture, and the organic layer was dried over Na2SO4 and concentrated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (CHCl3/MeOH) to obtain 5-(azetidin-3-yloxy)-2-(methoxymethyl)pyridine.
