실험 절차

2-Chloro-1-methylpyridinium iodide (0.048 g, 0.18 mmol), DIEA (0.045 mL, 0.25 mmol) and 2-amino-N-(4-p-tolylthiazol-2-yl)thiazole-5-carboxamide (0.04 g, 0.126 mmol) were added to a solution of 2-bromothiazole-5-carboxylic acid (26 mg, 0.126 mmol) in DMF (1 mL). The resulting solution was stirred at RT until completion of the reaction. Then a solid was precipitated with AcOEt and the solid was separated by centrifugation, yielding 2-bromo-N-(5-(4-p-tolylthiazol-2-ylcarbamoyl)thiazol-2-yl)thiazole-5-carboxamide (20 mg, 30%) as a solid that was used in the following step without further purification.
