Reaction Steps

A mixture comprising 213 g (1.17 mol) of 1,1,1-trifluoro-5-methyl-2,4-hexanedione, 242 g (1.64 mol) of ethyl orthoformate and 166 g (1.63 mol) of acetic anhydride, was heated and refluxed for 6 hours. The solvent was distilled off under reduced pressure to obtain 146 g (yield: 67%) of 3-ethoxymethylene-1,1,1-trifluoro-5-methyl-2,4-hexanedione.
