Participants

Reaction Steps

A mixture of 1-[2,3-bis(methylsulphenyl)-4-chlorophenyl]-3-cyclopropylpropan-1,3-dione (3.45 g) and acetic anhydride (3.37 g) in acetic acid was stirred and heated at reflux for 3 hours. It was cooled and evaporated to dryness. The residue was dissolved in toluene and re-evaporated to give 1-[2,3-bis(methylsulphenyl)4-chlorophenyl]-3-cyclopropyl-2-ethoxymethylenepropan-1,3-dione (4.1g) as a brown oil which was not further purified.
