Reaction Steps

A solution of 2.37 g of 2,6-dibromopyridine and 1.52 g of 3-hydroxybenzoic acid methyl ester in 10 ml of dimethylformamide is mixed with 6.6 g of cesium carbonate and heated to 120° C. with stirring for 3 hours. The reaction mixture is filtered on diatomaceous earth, rewashed with dichloromethane and the filtrate is concentrated by evaporation in a vacuum. The residue is distilled on a bulb tube at 140°-150° C. and 0.04 mbar. 2.98 g of 3-(6-bromo-2-pyridyloxy)-benzoic acid methyl ester of melting point 68°-69° C. is obtained.
