7 g (27.5 mmol) of methyl 3,3-diphenyl-2,3-epoxypropionate and 5.5 g (30.2 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 2 hours. The solvent was then distilled off, and the residue (10.7 g, 89%) was immediately reacted further.
