Reaction Steps

The mixture of 5-fluoro-2-[(5,6,7,8-tetrahydro-naphthalene-1-carbonyl)-amino]-indan-2-carboxylic acid ethyl ester (86) (190 mg, 0.50 mmol) and KOH (500 mg, 8.9 mmol) is dissolved in EtOH (5 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 (87) as a pale brown solid (178 mg, 100%).
