Reaction Steps

4-Chloro-2-(5-chloro-2-fluoro-phenyl)-pyrrolo[2,1-f][1,2,4]triazine (30 mg, 0.106 mmole), cesium carbonate (48.5 mg, 0.149 mmole), palladium (II) acetate (1.19 mg, 0.0053 mmole), BINAP (4.96 mg, 0.0080 mmole), and 4-amino-picoline (13.8 mg, 0.128 mmole) were combined in 4 ml dioxane (anh.) and heated to 90° C. with stirring overnight. The reaction mixture was filtered to remove solid material, the filtrate was evaporated to dryness, the residue was dissolved in chloroform (8 ml), washed with 0.5 M sodium hydroxide (1 ml), dried over sodium sulfate (anh.), evaporated to dryness, and then the residue was redissolved in dimethylformamide and purified by reversed phase HPLC. The product was isolated.
