Procedure

Methyl 5-(4-Acetoxy-3-methoxyphenyl)-penta-2E,4E-dienoate (400 mg, 1.45 mmol) [Example 1] was dissolved in 60 mL MeOH, 20 mL of 5% NaOH and 40 mL of water were added, and the mixture was stirred for 24 h at room temperature. The mixture was acidified to pH 2 with 5% HCl, methanol was evaporated and the compound was extracted with ethyl acetate. The organic layer was dried with Na2SO4 and evaporated.
