실험 절차

The mixture of 2-(2-cyclopent-1-enyl-3-methyl-benzoylamino)-5-fluoro-indan-2-carboxylic acid ethyl ester (151) (190 mg, 0.47 mmol) and KOH (600 mg, 10.7 mmol) is dissolved in EtOH (10 mL) and water (0.5 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 precipitate formed. The precipitate is filtered to give a pure product (152) as white solid (182 mg, 100%).
