실험 절차
6.5 g (19.5 mmol, 3 eq) of methyl triphenylphosphoranylideneacetate are added to a solution of 1.0 g (6.5 mmol, 1 eq) of vanillin in 15 ml of toluene. The reaction mixture is stirred for 1 hour at 90° C. The solvent is evaporated off and the residual oil is then chromatographed on silica gel (8/2 heptane/ethyl acetate). 1.12 g of methyl (E)-3-(4-hydroxy-3-methoxyphenyl)acrylate are obtained in oil form. Yield=83%
