To a solution of sodium (480 mg, 21 mmol) dissolved in 1-propanol (45 mL), was added 2-bromo-4-nitropyridine [(3.2 g, 19.2 mmol), J. Med. Chem. 46(7), 1273-1276; 2003] and the mixture was heated at 95° C. for 2 hours. The solvent was then evaporated under reduced pressure and the residue was suspended in chloroform and filtered. The filtrate was washed with water, dried over magnesium sulfate, and concentrated in vacuo to give an oily residue. The residue was distilled and title product was obtained during a temperature range of 145-150° C., as a solid in 58% yield, 2.67 g.
