Reaction Steps
To a stirred solution of 10 g of 2-chloro-5-nitropyridine and 2 g of dry methanol in 40 ml of dry tetrahydrofuran, 2.8 g of sodium hydride (about 60%, in oil) is added under cooling in an ice-water bath. The mixture is stirred at room temperature for 1 hour, and 30 ml of water is added. The mixture is extracted with three 40-ml portions of ethyl acetate, and the combined extracts are dried over magnesium sulfate. The solvent is distilled off to give 8.0 g of crude 2-methoxy-5-nitropyridine.
