Procedure
A mixture of 10.3 g of 4-[(2-methylbenzoyl)amino]benzoic acid and 32 ml of thionyl chloride is refluxed for 1.5 hours. The solution is concentrated under vacuum. Toluene is added and the solvent removed under vacuum. Toluene is added and the mixture chilled and filtered to give a yellow solid, m.p. 135°-141° C.
