Procedure

A mixture of 4.5 g of 6-[(2-methylbenzeneacetyl)amino]pyridine-3-carboxylic acid and 17 ml of thionyl chloride is heated on a steam bath for 1/2 hour. An additional 815 ml of thionyl chloride is added and the mixture refluxed for 0.5 hour. The volatiles are removed under vacuum and toluene (20 ml) added (twice) and the solvent removed under vacuum to give 5.3 g of a dark colored solid.
