実験手順
1.00 g 2,3-diamino-5-nitro-pyridine and 0.95 g 3,4-difluorobenzaldehyde were stirred in 60 ml nitrobenzene at 160° C. for 26 hrs. The solvent was removed under vacuum and the residue dissolved in 40 ml pyridine at 60° C. The solution was cooled in an ice bath. Precipitated product was isolated by filtration and dried to yield 0.5 g of the title product.
