Reaction Steps

To a solution of 1-({3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)azetidin-3-one (100 mg, 0.22 mmol), prepared using procedures similar to those described in Example 6, in dioxane (1.0 mL) was added hydroxylamine (0.10 mL, 50% solution in water, 1.5 mmol), and the resulting solution was heated at 60° C. for 18 h. The mixture was cooled to room temperature and the crude product was purified by reverse phase HPLC to afford 1-({3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)azetidin-3-one oxime (56 mg, 54% yield): 1HNMR (400 MHz, CDCl3), 8.43 (br s), 7.43-7.39 (m, 2H), 7.35-7.32 (dd, 1H), 7.19-7.15 (m, 1H), 6.87-6.81 (m, 1H), 6.65-6.59 (m, 1H), 4.89 (br s, 2H), 4.85 (br s, 2H); MS (EI) for C16H11F3IN3O2: 462 (MH+).
