Procedure

To a solution of 2-bromo-5-fluoroisonicotinic acid (5.2 g) in N,N-dimethylformamide (100 mL) were added potassium carbonate (9.8 g) and iodoethane (7.4 g) at room temperature, and this mixture was stirred at same temperature for 24 hours. This reaction mixture was poured into water, and this mixture was extracted with ethyl acetate. This organic layer was washed with water and brine, dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure to give the title compound (2.9 g).
