Reaction Steps

A mixture of 3-cyclopropyl-1-(2-phenylsulphenyl-4-trifluoromethylphenyl)propan-1,3-dione (6.0 g) and triethylorthoformate (4.9 g) in acetic anhydride was stirred and heated at reflux for 3 hours. It was cooled and evaporated. The residue was treated with toluene and re-evaporated to dryness to give 1-cyclopropyl-2-ethoxymethylene-3-(2-phenylsulphenyl-4-trifluoromethylphenyl)propan-1,3-dione (6.7 g) as a red oil.
