Diisopropylethylamine → N-({3-[(3-bromo-5-chlorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)-4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide

Participants

Reaction Steps

To a solution of ({3-[(3-bromo-5-chlorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)amine (667 mg, 1.828 mmol), 4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxylic acid (506 mg, 1.828 mmol) and diisopropylethyl amine (0.669 mL, 3.83 mmol) in DMF (20 ml) was added HATU (695 mg, 1.828 mmol) and the mixture was stirred for 30 minutes. The 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-bromo-5-chlorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)-4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (589 mg, 0.944 mmol, 52% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.74 (t, 1H), 7.95 (s, 1H), 7.40-7.51 (m, 2H), 7.37 (t, 1H), 7.09 (t, 1H), 7.01 (t, 1H), 5.46 (s, 2H), 4.46 (d, 2H), 3.35 (t, 2H), 0.72 (t, 2H), −0.12 (s, 9H).
