Procedure

6-Amino-2-(4-fluoro-phenyl)-5-isopropoxy-benzofuran-3-carboxylic acid methylamide, prepared according to Example 16 (55 mg, 161 μmol) was dissolved in anhydrous diethyl ether (2 mL). Triethylamine (25 μL, 193 μmol) was added to the reaction mixture, followed by the slow addition of dimethylsulfate (17 μL, 177 μmol). Water (1 mL) was added after 2 hours. The reaction was concentrated to dryness, and the crude product was purified on HPLC (reverse phase) to provide 32 mg (56%) of pure product.
