Reaction Steps

To a solution of 2-azido-4-chloro-N-[(4-chloro-3-{[3-cyano-5-(difluoromethyl)phenyl]oxy}-2-fluorophenyl)methyl]-1H-imidazole-5-carboxamide trifluoroacetate (39.0 mg, 0.079 mmol) in THF (6 ml) was added water (2.83 μl, 0.157 mmol) followed by trimethyl phosphine (2.0 M solution in THF) (0.039 ml, 0.079 mmol) and the reaction mixture was stirred at RT for 15 minutes. The solvent was removed and the crude material was purified via reverse phase HPLC to give 2-amino-4-chloro-N-[(4-chloro-3-{[3-cyano-5-(difluoromethyl)phenyl]oxy}-2-fluorophenyl)methyl]-1H-imidazole-5-carboxamide trifluoroacetate (28 mg, 0.048 mmol, 61.0% yield). 1H NMR (DMSO-d6) δ ppm 7.76-7.88 (m, 2H) 7.68 (s, 1H) 7.39-7.54 (m, 2H) 7.31 (t, 1H) 6.84-7.20 (m, 1H) 5.97 (br.s., 2H) 4.45 (d, 2H). LC-MS (ES+) m/z 470.05 [M+H].
