Procedure
A mixture of 1-[2-(methylsulphenyl)-3-(methylsulphenylmethyl)-4-chlorophenyl]-3-cyclopropylpropan-1,3-dione (1.5 g) and triethylorthoformate (8 ml) in acetic anhydride (25 ml) was heated at reflux temperature for 4 hours. The excess reagent and solvent were evaporated under reduced pressure, yielding 1-[2-(methylsulphenyl)-3-(methylsulphenylmethyl)-4-chlorophenyl]-2-ethoxymethylene-3-cyclopropylpropan-1,3-dione as a brown oil (2.3 g).
