Versuchsvorschrift

A mixture of methyl 1-(4-fluorophenyl)-indole-5-carboxylate 1m (0.58 g, 2.15 mmol) and LiOH H2O (0.36 g, 8.6 mmol) in THF (15 mL) and H2O (10 mL) was stirred at room temperature for 5 days. Aqueous 10% HCl solution was added to the reaction mixture to adjust pH=3˜4. The resulting mixture was extracted with EtOAc (2×). The organic solution was washed with aq. NaCl, dried over Na2SO4 and concentrated to give In (0.5 g).
