Potassium Carbonate → Methyl 2-(2-chloro-4-hydroxymethyl-6-propylphenoxy)-2-(3,4-methylenedioxyphenyl)acetate

Participants

Reaction Steps

To a solution of 0.280 g (1.40 mmol) of the product of step C and 0.762 g () of methyl α-bromo-3,4-methylenedioxyphenylacetate in 3.0 mL of acetone was added 0.386 g (2.80 mmol) of finely powdered potassium carbonate and the mixture was stirred and heated at reflux for 2 hours. At this point, the reaction mixture was cooled to room temperature, filtered, and evaporated in vacuo. The residue was purified on a silica gel flash chromatography column eluted with 30% EtOAc-hexane. Evaporation of the purified fractions and solvent removal in vacuo afforded 0.445 g (81%) of the title compound.
