6 g (19.3 mmol) of methyl 3,3-di(4-ethylphenyl)-2,3-epoxypropionate (crude) and 3.52 g (19.3 mmol) of 2-(3,4-dimethoxyphenyl)ethanol were dissolved in 20 ml of dichloromethane and, at room temperature, 5 drops of boron trifluoride etherate were added. The solution was stirred for 1.5 hours. The solvent was then distilled off, and the residue, a pale yellow oil (8.66 g, 91%), was immediately reacted further.
