Vorschrift

A mixture of methyl-3(3-allyl-4-hydroxyphenyl)propionate (12.3 g), anhydrous potassium carbonate (13.8 g), and allylbromide (8.64 mls) in acetone (300 ml) was stirred at ambient temperature for two days. The reaction mixture was filtered and the residue washed with acetone. The filtrate and washings were combined and evaporated to give methyl-3-(3-allyl-4-allyloxyphenyl)proprionate as a pale yellow oil (14.0 g); NMR: 2.58(2H,t), 2.75(2H,t), 3.31(2H,d), 3.55(3H,s), 4.52(2H,d), 4.95-5.45(4H,m), 5.85-6.11(2H,m), 6.85(1H,d) and 7.0(2H,m).
