Procedure
To an EtOH (50 mL) solution of butyl (E)-3-[2-methyl-4-({5-[(4-methylbenzyl)-oxy]pyridin-2-yl}oxy)phenyl]prop-2-enoate (4.67 g) was added 5 M NaOH (3.25 mL) at room temperature. After stirring for 14 hours, 5 M NaOH (1.08 mL) and water (25 mL) were added, and then the reaction mixture was refluxed for 2 hours. The solvent was removed under reduced pressure. The residue was dissolved in water, and neutralized with 6 M HCl at 0° C. The resulting precipitate was collected by filtration and dried to afford (E)-3-[2-methyl-4-({5-[(4-methylbenzyl)oxy]pyridin-2-yl}oxy)phenyl]prop-2-enoic acid as a colorless solid (4.06 g).
