Reaction Steps

The mixture of 3-chloro-4-hydroxybenzaldehyde (0.783 g, 5 mmol) and ethyl 2-(triphenylphosphoranylidene)propionate (2.72 g, 7.5 mmol) in anhydrous tetrahydrofuran (25 mL) was heated at 60° C. under nitrogen for 4 hours. The solvent was removed in vacuo and purified by silica gel chromatography (40% EtOAc in hexanes) to provide ethyl 3-(3-chloro-4-hydroxyphenyl)-2-methylacrylate (515) (1.11 g, 95.2%) as a white solid.
