Procedure

To the mixture of 2-aminopyridin-3-ol (500 mg) and DMF (dry) (15 mL) was added NaH (60%, 200 mg) at room temperature and the mixture was stirred at room temperature for 20 min. 1-(Bromomethyl)-3-chlorobenzene (933 mg) was added and the mixture was stirred at the same temperature for 1 hr. Water and EtOAc were added and the extracted organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give the title compound (1.01 g) as a brown crystalline solid.
