To a solution of 5-chloro-2-thiophenecarboxylic acid (195 mg, 1.20 mmol) and triethylamine (0.400 mL, 2.87 mmol) in DMF (5 mL), BOP (550 mg, 1.24 mmol) was added. After 5 min of stirring, a solution of (1-(5-bromopyridin-2-yl)-1H-imidazol-4-yl)methanamine (253 mg, 1.00 mmol) in DMF (5 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, and concentrated in vacuo. The residue was purified by HPLC to give N-((1-(5-bromopyridin-2-yl)-1H-imidazol-4-yl)methyl)-5-chlorothiophene-2-carboxamide (85 mg).
