Reaction Conditions

Reaction Steps

4.0 g (20.6 mmol) of 3-butoxy-4-hydroxybenzaldehyde and 13.25 g (30.9 mmol) of (methoxy(methoxycarbonyl)methyl)triphenylphosphonium chloride are suspended in 40 ml of tetrahydrofuran. 6 ml (42 mmol) of triethylamine are added and then the reaction medium is stirred at 40° C. for 16 hours. The reaction medium is filtered and then the solvents are evaporated. 50 ml of diethyl ether are added and the mixture is stirred at ambient temperature for 10 minutes and then filtered. After evaporation of the solvents, the residue is taken up in a heptane/ethyl acetate 8/2 mixture and then filtered through a silica patch (2 cm). 5.3 g of methyl (Z)-3-(3-butoxy-4-hydroxyphenyl)-2-methoxyacrylate are obtained after evaporation of the solvents.
