A mixture of 26.1 g of 2-aminobenzoic acid, 36.5 g of 4-chloro-1-phenyl-1-butanone, 0.5 g of p-toluenesulfonic acid and 250 ml of xylene were refluxed with a water trap. After the reaction was complete, the solvent was removed by distillation and the remaining solid was recrystallized from ethanol. Yield: 41.1 g (81.5%), melting point 152° C.
