PROCEDURE
实验过程
A mixture of 6-chloro-imidazo[1,2-b]pyridazine-2-carboxylic acid (600 mg), HBTU (900 mg), DIEA (1 mL) and 5-(3-chloro-4-trifluoromethyl-phenyl)-1H-benzoimidazol-2-ylamine hydrobromide salt (794 mg) in DMF (5 mL) was heated at 80° C. for 1 hour with stirring. After cooling the reaction mixture to room temperature, an aqueous sodium bicarbonate solution was added, and the mixture was stirred for 30 minutes at room temperature. The solid was filtered, washed with water, and dried under vacuum to get 6-chloro-imidazo[1,2-b]pyridazine-2-carboxylic acid [5-(3-chloro-4-trifluoromethyl-phenyl)-1H-benzoimidazol-2-yl]-amide (890 mg). LCMS (m/z): 491.8.
