Procedure

To a solution of 5-chloro-thiophene-2-carboxylic acid 1-5 (72 mg, 0.44 mmol) and triethylamine (0.150 mL, 1.10 mmol) in DMF (5 mL), BOP (235 mg, 0.53 mmol) was added. After 5 min of stirring, the solution was added to the sample of (1-(4-iodophenyl)-2-(methylthio)-1H-imidazol-4-yl)methanamine (127 mg, 0.37 mmol) in a flask. After being 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 dissolved in CH3CN (8 mL), H2O (10 mL) was added to induce precipitation, which was collected and dried on vacuum to give 5-chloro-N-((1-(4-iodophenyl)-2-(methylthio)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide (56 mg).
