Versuchsvorschrift

To a solution of 1-({3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)azetidin-3-amine (0.10 M in acetonitrile, 1.0 mL, 0.09 mmol), prepared using procedures similar to those described in Example 2, in 1:1 ratio of methanol and tetrahydrofuran (2.0 mL) was added formaldehyde (37% wt, 6.7 μL, 0.09 mmol) followed by sodium cyanoborohydride (11.0 mg, 0.18 mmol). The reaction mixture was stirred at room temperature for 16 h, at which time it was quenched with saturated aqueous ammonium chloride. The solution was then purified directly by reverse phase HPLC to afford the title compound (14.9 mg). 1H NMR (400 MHz, CDCl3): 8.13 (br s, 1H), 7.35 (d, 1H), 7.30 (d, 1H), 7.09-7.04 (m, 1H), 6.84-6.78 (m, 1H), 6.60-6.54 (m, 1H), 4.46-4.33 (br m, 4H), 3.93 (br m, 1H), 2.64 (s, 3H). MS (EI) for C17H15F3IN3O: 462 (MH+).
