実験手順

3-{[3-(aminomethyl)-6-chloro-2-fluorophenyl]oxy}-5-methylbenzonitrile (0.053 g, 0.181 mmol), 4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxylic acid (0.050 g, 0.181 mmol) and DIPEA (0.063 mL, 0.361 mmol) were combined in THF (2 mL) and treated with HATU (0.076 g, 0.199 mmol) at 25° C. overnight with stirring. The reaction mixture was concentrated to dryness, dissolved in DCM, washed with water, dried over MgSO4, filtered and concentrated to dryness. The residue was dissolved in DCM (2.5 mL) and treated with TFA (2.5 mL) at 25° C. for 3 days. The reaction mixture was concentrated to dryness, dissolved in DCM, washed with saturated aqueous NaHCO3, dried over MgSO4, filtered and concentrated to dryness. The resultant solid was recrystallized from boiling IPA, cooled in an ice bath and filtered to give 4-chloro-N-({4-chloro-3-[(3-cyano-5-methylphenyl)oxy]-2-fluorophenyl}methyl)-1H-imidazole-5-carboxamide (0.043 g, 0.103 mmol, 56.8% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 13.17 (br. s., 1H), 8.25 (m, 1H), 7.78 (s, 1H), 7.50 (m, 1H), 7.44 (s, 1H), 7.36 (t, J=8.03 Hz, 1H), 7.22 (s, 1H), 7.13 (s, 1H), 4.54 (d, J=5.36 Hz, 2H), 2.33 (s, 3H). LC-MS (ES−) m/z 417.04, 419.01 [M−1]. LC-MS (ES+) m/z 418.79, 420.06 [M+H].
