Reaction Steps

To a well stirred solution of 6-aminonicotinonitrile (0.631 g, 5.29 mmol) in dry DMA (10 ml), CS2CO3 (2.157 g, 6.62 mmol) and 2-chloro-3-nitropyridine (0.700 g, 4.415 mmol) were added and reaction mixture was heated at 80° C. under nitrogen atmosphere for 24 h. After completion the reaction mixture was cooled to room temperature, extracted with ethyl acetate (2×100 ml), combined organic layers washed with water (2×50 ml) and brine, dried (Na2SO4), filtered and concentrated under reduced pressure to yield 543 mg of the product.
