실험 절차

To a mixture of 3-(imidazo[1,2-b]pyridazin-6-ylethynyl)aniline (93.6 mg, 0.4 mmol, 1 eq) and m-toluic acid (55 mg, 1 eq) in anhydrous dichloroethane (4 mL) under nitrogen atmosphere was added 4-(dimethylamino)pyridine (10 mg, 0.2 eq) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (92.2 mg, 1.2 eq). After the reaction was stirred at 60° C. for four hours and was cooled to room temperature, white precipitates were observed. It was filtered directly to give a white solid. This solid was further subject to a gradient column chromatography (MeOH-DCM 1:50 to 1:20) to yield N-[3-(imidazo[1,2-b]pyridazin-6-ylethynyl)phenyl]-3-methylbenzamide as a white solid in amount of 85 mg.
