Procedure

In 10 ml of methanol was dissolved 380 mg of ethyl 1-hydroxy-4-(p-heptyloxybenzyloxy)-2-indaneacetate obtained in Example 100 and, 2.5 ml of a 5% sodium hydroxide solution was added thereto followed by stirring at room temperature for 8 hours. The system was rendered acidic with 20% hydrochloric acid and extracted with ethyl acetate. The ethyl acetate layer was washed subsequently with water and then a saturated saline aqueous solution, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The crystalline residue was recrystallized from ethyl acetate-hexane to obtain 230 mg of 1-hydroxy-4-(p-heptyloxybenzyloxy)-2-indaneacetic acid.
