Participants

Reaction Steps

A mixture of 1-[2-chloro-4-(methylsulphonyl)phenyl]pentan-1,3-dione (7.0 g), triethyl orthoformate (7.2 g) and acetic anhydride was stirred and heated at reflux for 4 hours. The mixture was cooled and evaporated to dryness. Toluene was added to the residue and then re-evaporated to give 1-[2-chloro-4-(methylsulphonyl)phenyl]-2-ethoxymethylenepentan-1,3-dione (7.18 g) as a sticky orange solid which was not purified further.
