Procedure

A mixture of 3-(phenylamino)-4-methoxybenzoic acid, methyl ester (0.4 g, 1.6 mmol), methanol (10 mL), and 4N sodium hydroxide (15 mL) was stirred and heated to reflux. After 2 hours, the methanol was removed by rotary evaporator and the residual aqueous suspension stirred and acidified with 4N HCl. The precipitate was filtered off, rinsed with water, and dried to afford the product (0.35 g); m.p. 198-200° C.
