실험 절차

To a solution of 5-chlorothiophene-2-carboxylic acid 1-5 (1.10 g, 6.76 mmol) and TEA (2.0 mL, 14.4 mmol) in DMF (12 mL), BOP (3.30 g, 7.45 mmol) was added. After being mixed for 5 min, the solution was added to the compound 4-aminomethylimidazole II-2 prepared above (0.604 g, 6.22 mmol) in a round bottom flask. The mixture was then stirred at room temperature overnight. It was purified by HPLC to give 5-chloro-N-((1H-imidazol-4-yl)methyl)thiophene-2-carboxamide 3-1 (1.52 g). MS 242.0 and 244.0 (M+H, Cl pattern).
