Procedure
An 800 mg portion of [4-[[4-(4-pyridinyl)-2-pyrimidinyl]amino]phenoxy]acetic acid, ethyl ester was dissolved in 100 ml of ethanol and 10.7 ml of 1N sodium hydroxide was added. The mixture was stirred for 2 hours, the solvent removed and the residue dissolved in 5 ml of water. The pH was adjusted to 7.0 with 1N hydrochloric acid and the solid collected, washed with water and dried. The solid was recrystallized from dimethylformamide-ethanol, giving 600 mg of the desired product as yellow crystals, mp 308°-310° C.
