Reaction Steps
4-Chloro-3-nitropyridine (2.0 g, 12.62 mmol) prepared in Step 1 of Preparation 1 was added to a suspension of 4-fluorobenzyl alcohol (2.04 ml, 18.92 mmol), potassium carbonate (1.74 g, 12.62 mmol), and potassium hydroxide (2.38 g, 50.48 mmol) in anhydrous toluene (100 ml). A catalytic amount of tris[2-(2-methoxyethoxy)ethyl]amine was added to the reaction mixture, which was then stirred for 1 hour at room temperature. The reaction mixture was filtered and then concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography (ethyl acetate/n-hexane=1/1, (v/v)) to give the titled compound as a white solid (2.5 g, 86.3%).
