Participants

Reaction Steps

Preparation of compound 39(c) (5-(2,2-dimethyl-4-oxo-4H-benzo[1,3]dioxin-7-ylmethoxy)-2-(4-fluoro-phenyl)-6-(methanesulfonyl-methyl-amino)-benzofuran-3-carboxylic acid methylamide). Potassium carbonate (0.19 g, 1.38 mmol) and compound 39(b) (0.25 g, 0.917 mmol) were added to a solution of compound 38(d) (0.18 g, 0.459 mmol, which can be prepared according to Example 38 step d above), in acetonitrile (15 mL). The reaction mixture was refluxed for 4 hours and then concentrated in vacuo. The crude product was dissolved in ethyl acetate and washed with water. The organic layer was concentrated to a solid, which was triturated in 20% ethyl acetate/hexanes, filtered, and dried to provide 240 mg (90%) of the desired product as an off-white solid.
