Procedure

To a solution of 6-(6-methoxypyridin-3-yloxy)-1-naphthoate (480 mg, 1.55 mmol) in THF (155 mL) at RT was added 1M aqueous LiOH (31 mL). The reaction was stirred until the reaction was completed. THF was removed in vacuo. The aqueous layer was acidified using 6M aqueous HCl to pH=6-7 and extracted with EtOAc. The aqueous layer was further acidified to pH=5 and extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo to give the title compound, which was used without further purification.
