To a solution of ({3-[(3-butyl-5-chlorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)amine (105 mg, 0.307 mmol), 4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxylic acid (85 mg, 0.307 mmol) and HATU (117 mg, 0.307 mmol) in DMF (3 ml) was added diisopropylethyl amine (0.107 ml, 0.614 mmol) and the reaction mixture was stirred at rt for 45 minutes. 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 N-({3-[(3-butyl-5-chlorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)-4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (151 mg, 0.251 mmol, 82% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.73 (t, 1H), 7.95 (s, 1H), 7.39-7.46 (m, 1H), 7.34 (t, 1H), 6.99 (s, 1H), 6.70 (s, 1H), 6.66 (s, 1H), 5.47 (s, 2H), 4.45 (d, 2H), 3.36 (t, 2H), 2.50 (t, 2H), 1.46 (t, 2H), 1.16-1.28 (m, 2H), 0.82 (t, 3 H), 0.73 (t, 2H), −0.12 (s, 9H).
