1M LiHMDS solution (9.25 mL, 9.25 mmol) in THF was added drop wise to a cooled solution of 4-Methyl-pyridin-3-ylamine (1 g, 9.25 mmol) in THF (10 mL) at 0° C. under nitrogen atmosphere. The resulting mixture was added drop wise to a solution of 1-fluoro-2-nitro-benzene (0.98 mL, 9.25 mmol) in THF at 0° C. The resulting reaction mass was stirred at room temperature overnight. The reaction was monitored by TLC (50% ethyl acetate in hexane). The reaction mixture was diluted with ethyl acetate and concentrated under reduced pressure. The crude residue was purified by column chromatography on silica gel (50% ethyl acetate in hexane) to afford 600 mg of the product (28.32% yield).
