Reaction Steps
The corresponding free acid, 2-(4-hydroxyphenylamino)benzoic acid, yellow solid m.p. 233° C.(decompn.) was prepared by hydrogenation of 5 g of 2-(4-benzyloxyphenylamino)benzoic acid in 250 ml of ethanol containing 2 ml of concentrated hydrochloric acid and 2 g of palladium-on-carbon catalyst. The benzyloxy compound was in turn prepared by reaction of 2-chlorobenzoic acid and 4-benzyloxyaniline.
