Methyl 3-isopropoxy-5-(3-pyridin-3-ylpropoxy)benzoate (2.70 g) was dissolved in a mixed solvent of THF (30 ml) and methanol (30 ml), and 1N aqueous sodium hydroxide solution (25 ml) was added to the mixed solution. The mixture was stirred overnight at room temperature and concentrated under reduced pressure to dryness. 1N Aqueous hydrochloric acid solution (25 ml) was added thereto, and the precipitated crystals were collected by filtration and washed with water to give 3-isopropoxy-5-(3-pyridin-3-ylpropoxy)benzoic acid (1.55 g, 60%) as colorless crystals.
