실험 절차

The mixture of 2-(2-isopropoxy-3-methyl-benzoylamino)-5-methoxy-indan-2-carboxylic acid ethyl ester (92) (410 mg, 1 mmol) and KOH (1 g, 18 mmol) is dissolved in EtOH (8 mL) and water (1 mL) under a water bath. The water bath is removed when KOH is completely dissolved and the resulting reaction solution is stirred at RT for 8 h. After concentration in vacuo, the residue is dissolved in water (20 mL) and acidified with conc. HCl until no more white precipitate formed. The precipitate is filtered to give a pure product (93) as white solid (400 mg, 100%).
