Reaktionsschritte

A solution of 3.04 g (15.8 mmol) of methyl 4-hydroxy-3-propenylbenzoate (Example 7, Step B) was refluxed with anhydrous potassium carbonate (4.37 g, 2 equiv) and allyl bromide (3.5 mL. 2.5 equiv) in acetone overnight. The mixture was filtered through celite and the filter cake was washed with more acetone and dichloromethane. After removing the solvents, the resulting oil was distilled under high vacuum to give 3.2 g (87%) of the title compound.
