반응 단계
A mixture comprising 17.2 g (110 mmol) of 2,6-dimethyl-3,5-heptanedione, 22.8 g (153 mmol) of ethyl orthoformate and 31.5 g (309 mmol) of acetic anhydride, was reacted for 2 hours at 110° C. The solvent was distilled off under reduced pressure to obtain 11.5 g (yield: 49%) of 4-ethoxymethylene-2,6-dimethyl-3,5-heptanedione.
