Reaction Steps

4-chloro-N-({4-chloro-3-[(3-chloro-5-cyanophenyl)oxy]-2-fluorophenyl}methyl)-2-ethyl-1H-imidazole-5-carboxamide was prepared in a similar manner as described herein from 3-chloro-5-({6-chloro-2-fluoro-3-[(methylamino)methyl]phenyl}oxy)benzonitrile (0.713 g, 2.29 mmol), 4-chloro-2-ethyl-1H-imidazole-5-carboxylic acid (0.400 g, 2.29 mmol), HATU (1.133 g, 2.98 mmol), DIPEA (0.520 mL, 2.98 mmol) and DMF (12 mL). Purification was accomplished by silica gel chromatography (0-5% MeOH (2M NH3) in CH2Cl2) to afford the title compound (0.622 g, 58%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 12.74 (s, 1H), 8.09 (br. s., 1H), 7.81-7.84 (m, 1H), 7.48-7.53 (m, 2H), 7.45-7.47 (m, 1H), 7.33-7.40 (m, 1H), 4.54 (d, 2H), 2.60 (q, 2H), 1.18 (t, 3H). ES-LCMS: m/z 467.0, 469.0 (M+H).
