Versuchsvorschrift

To a solution of methyl 6-[2-(butan-2-yl)-6-chloro-5-methoxyindol-1-ylmethyl]pyridine-2-carboxylate (200 mg) in tetrahydrofuran (3.08 mL) and methanol (1.32 mL) was added 2 mol/L aqueous sodium hydroxide solution (0.775 mL) at room temperature, followed by stirring for 2.5 hours. To the reaction mixture was added 1 mol/L hydrochloric acid (1.55 mL). To the mixture were added water and ethyl acetate to separate the organic layer. The organic layer was washed with water twice, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure to obtain the title compound (190 mg). 1H-NMR (DMSO-d6) δ ppm: 0.77 (3H, t, J=7.4 Hz), 1.17 (3H, d, J=6.9 Hz), 1.40-1.70 (2H, m), 2.80-2.95 (1H, m), 3.83 (3H, s), 5.45-5.65 (2H, m), 6.30 (1H, s), 6.70 (1H, d, J=7.3 Hz), 7.20 (1H, s), 7.55 (1H, s), 7.80-7.95 (2H, m), 13.00-13.50 (1H, br).
