To a solution of 3-{[3-(aminomethyl)-6-chloro-2-fluorophenyl]oxy}-5-(trifluoromethyl)benzonitrile (85.0 mg, 0.247 mmol), 4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxylic acid (68.3 mg, 0.247 mmol) and HATU (94 mg, 0.247 mmol) in DMF (5 ml) was added diisopropylethyl amine (0.086 ml, 0.493 mmol) and the reaction mixture was stirred for 30 minutes at rt. The reaction mixture was diluted with EtOAc and washed with water. The solvent was removed and the crude material was purified via silica gel chromatography to give 4-chloro-N-[(4-chloro-3-{[3-cyano-5-(trifluoromethyl)phenyl]oxy}-2-fluorophenyl)methyl]-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (97 mg, 0.161 mmol, 65% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.74 (t, 1H), 8.09 (s, 1H), 7.95 (s, 1H), 7.74 (s, 1H), 7.70 (s, 1H), 7.43-7.53 (m, 1H), 7.39 (t, 1H), 5.47 (s, 2H), 4.46 (d, 2H), 3.35 (t, 2H), 0.59-0.81 (m, 2H), −0.12 (s, 9H).
