Procedure

To a mixture of the 3-{[(1-methylethyl)amino]methyl}azetidin-3-amine hydrochloride (20 mg, 0.079 mmol) in saturated sodium bicarbonate solution (1.0 mL) and dioxane (1.0 mL) was added 3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]benzoyl fluoride (31 mg, 0.079 mmol), prepared using procedures similar to those described in Reference 1, and the resulting mixture was stirred at room temperature for 18 h. The reaction mixture was diluted with water (5 mL) and extracted with ethyl acetate (3×5 mL). The combined extract was washed with water then brine solution (5 mL each), dried over sodium sulfate, filtered and concentrated to give an oily residue which was purified by reverse phase HPLC to afford 1-({3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)-3-{[(1-methylethyl)amino]methyl}azetidin-3-amine (15 mg, 37% yield). 1H NMR (400 MHz, d4-Methanol): 7.46-7.43 (dd, 1H), 7.35-7.33 (dd, 1H), 7.31-7.27 (m, 1H), 7.08-7.01 (dd, 1H), 6.63, 6.58 (td, 1H), 4.09-4.07 (d, 1H), 3.91-3.85 (dd, 2H), 3.76-3.73 (d, 1H). 2.80-2.74 (m, 1H), 2.73 (s, 2H), 1.07-1.05 (d, 6H); MS (EI) for C20H22F3IN4O: 519 (MH+).
