Procedure
Potassium carbonate (0.050 g, 0.357 mmol) followed by 4-(chloromethyl)thiazole hydrochloride (0.041 g, 0.238 mmol) were added to a solution of 2-(4-fluoro-phenyl)-5-isopropoxy-6-methanesulfonylamino-benzofuran-3-carboxylic acid methylamide (0.050 g, 0.119 mmol, which can be prepared according to one of the procedures described in Example 21 above), dissolved in acetonitrile (10 mL). The reaction was refluxed for 1 hour with no visible product formation observed by TLC, so potassium iodide (0.020 g, 0.120 mmol) was added to the reaction. The mixture was refluxed for an additional 2 hours, and then cooled to room temperature. The reaction mixture was concentrated, and the residue was dissolved in ethyl acetate and washed with water. The product was concentrated and purified by flash chromatography (silica gel, ethyl acetate/hexanes gradient) to provide 30 mg (48%) of the desired product as a white solid.
