Procedure

A mixture of 0.88 gm (3.79 mMol) 8-nitro-1,2,3,4-tetrahydro-2-dibenzofuranamine, 0.89 gm (5.68 mMol) iodoethane and 1.58 gm (11.4 mMol) potassium carbonate in 50 mL acetone was heated at reflux for 3 hours. The reaction mixture was concentrated under reduced pressure and the residue dissolved in water. This mixture was extracted well with chloroform. The organic phases were combined, dried over potassium carbonate and concentrated under reduced pressure. The residue was subjected to radial chromatography (silica gel, 2 mm). Fractions containing product were combined and concentrated under reduced pressure to provide 0.49 gm (45%) 8-nitro-1,2,3,4-tetrahydro-2-diethylaminodibenzofuran as a yellow oil.
