Procedure

3,4-Difluoro-2-[(2-fluoro-4-iodophenyl)amino]benzoic acid (362 mg, 0.921 mmol), prepared using procedures similar to those described in U.S. Pat. No. 7,019,033, 4-(dimethylamino)pyridine (337 mg, 2.76 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (212 mg, 1.11 mmol) were dissolved in DMF (3 mL). The mixture was stirred at ambient for 5 minutes and then 3-(1-hydroxyethyl)azetidin-3-ol hydrochloride (0.922 mmol) in DMF (2 mL) was added and the mixture was stirred for 15 h. The mixture was partitioned between ethyl acetate and 5% lithium chloride. The organic portion was washed with 20% citric acid, saturated sodium bicarbonate and brine, then was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. Column chromatography (silica gel, 80% ethyl acetate in hexanes) gave 1-({3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)-3-(1-hydroxyethyl)azetidin-3-ol (296 mg, 0.602 mmol, 65% yield): MS (EI) for C18H16F3IN2O3: 493 (MH+).
