Participants

Reaction Steps

Diisopropylethylamine (407 μL, 2.34 mmol) and ethyl iodine (187 μL, 2.34 mmol) were added to a solution of 6-amino-2-(4-fluoro-phenyl)-5-isopropoxy-benzofuran-3-carboxylic acid methylamide, prepared according to Example 16 (200 mg, 584 μmol) in dry acetonitrile (8 mL). The reaction was monitored under analytical LC/MS conditions and quenched by addition of water (4 mL). After concentration to dryness, the crude product was purified by preparative HPLC (reverse phase C18, acetonitrile/water plus 0.1% acetic acid), affording 97 mg (45%) of the 6-ethylamino-2-(4-fluoro-phenyl)-5-isopropoxy-benzofuran-3-carboxylic acid methylamide and 63 mg (27%) of 6-diethylamino-2-(4-fluoro-phenyl)-5-isopropoxy-benzofuran-3-carboxylic acid methylamide.
