Procedure

To a solution of 5-chloro-2-thiophenecarboxylic acid 1-5 (165 mg, 1.01 mmol) and triethylamine (0.300 mL, 2.16 mmol) in DMF (5 mL), BOP (472 mg, 1.07 mmol) was added. After 5 min of stirring, a solution of (1-(3-fluoro-4-iodophenyl)-1H-imidazol-4-yl)methanamine (268 mg, 0.845 mmol) in DMF (4 mL) was added. The mixture was stirred at room temperature overnight. H2O and EtOAc were added. The organic phase was separated, washed with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo. The residue was purified by HPLC to give 5-chloro-N-((1-(3-fluoro-4-iodophenyl)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide (83 mg).
