Reaction Steps

A mixture of 1.43 gm (5.10 mMol) ethyl 2-acetoxy-2-(5-fluorobenzofur-7-yl)acetate, 7.31 gm (40.8 mMol) hexamethylphosphoramide, 0.20 gm (6.12 mMol) methanol, and 153 mL (15.3 mMol) samarium(II) iodide tetrahydrofuran complex (0.1 M in tetrahydrofuran) was stirred at room temperature under a nitrogen atmosphere for 15 minutes. The reaction mixture was then diluted 10 fold with ethyl acetate, washed with water, and concentrated under reduced pressure to provide 1.09 gm (96%) of the desired compound.
