実験手順
A mixture of (E)-methyl 4-(3,3,3-trifluoroprop-1-enyl)-2-methoxybenzoate (340 mg, 0.0013 mol), MeOH (20 mL), and 2 N aqueous NaOH solution (1.5 mL) was stirred at 65° C. overnight. The solvents were removed under reduced pressure and the residue was treated with water, acidified with 1N HCl to pH 2-3, and extracted with EtOAc (50 mL×3). The combined organic layers were washed with brine, dried (Na2SO4), filtered and concentrated under vacuum to give the product as a white solid. LC-MS: 2.59 min, 244.8 (M−1).
