To a solution of 3-{[3-(aminomethyl)-6-chloro-2-fluorophenyl]oxy}-5-cyclopropylbenzonitrile (95 mg, 0.299 mmol), 2-(bis{[(1,1-dimethylethyl)oxy]carbonyl}amino)-4-chloro-1H-imidazole-5-carboxylic acid (120 mg, 0.299 mmol) and HOBT (45.7 mg, 0.299 mmol) in DMF (3 ml) was added EDC (57.2 mg, 0.299 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 bis(1,1-dimethylethyl)(4-chloro-5-{[({4-chloro-3-[(3-cyano-5-cyclopropylphenyl)oxy]-2-fluorophenyl}methyl)amino]carbonyl}-1H-imidazol-2-yl)imidodicarbonate (165 mg, 0.250 mmol, 84% yield) was used directly in the next step. LC-MS (ES+) m/z 660 [M+H].
