실험 절차

A solution of 0.63 g of 2,6-difluoropyridine in 0.2 mL of formamide was stirred for 3 hours at 150° C. The reaction mixture was cooled to room temperature, to which were added water (100 mL) and ethyl acetate (100 mL×3) for extraction. The extract solution was dried over anhydrous magnesium sulfate, followed by concentration to give powdery precipitate of 2-fluoro-6-(formylamino)pyridine. The powdery product was collected by filtration and dried for 2 hours at 40° C. under reduced pressure (0.4 g).
