Procedure

To a stirred solution of 3-Fluoro 2-nitro pyridine (1.6 g, 0.01126 mol) in dry Acetonitrile (20 ml) was added 4-Ethyl-2-methoxy phenol (1.71 g, 11.3 mmol) in dry acetonitrile (10 ml) followed by potassium hydroxide (0.696 g, 12.4 mmol). The reaction mixture was heated to 80° C. and maintained for 2 hours. The solvent was evaporated and taken in ethyl acetate (200 ml). The organic layer was washed with water followed by brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give 2.6 g of crude product purified by column chromatography (5% Ethyl acetate in Petroleum ether) to yield: 1.75 g (56%) of title compound.
