Procedure

The mixture of 2-[(4-fluoro-naphthalene-1-carbonyl)-amino]-indan-2-carboxylic acid ethyl ester (43) (180 mg, 0.48 mmol) and KOH (600 mg, 10.7 mmol) is dissolved in EtOH (10 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 6 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 (44) as white solid (174 mg, 100%).
