A solution of 0.45 g (1.2 mmol) of 4-[6-(2,3-dimethoxyphenyl)hexyloxy]-2-hydroxybenzoic acid methyl ester in 25 mL of methanol and 8 mL of 1N sodium hydroxide was refluxed for 7 hours. Workup as in Example 24 and recrystallization from methanol gave 0.36 g (82% yield), mp 115°-116° of 4-[6-(2,3-dimethoxyphenyl)hexyloxy]-2-hydroxybenzoic acid.
