Komponenten

Versuchsvorschrift

A mixture of the 3-(N-benzyloxycarbonylpyrrolidin-2-ylmethyl)-1H-indole (2.00 mmol) and 10% palladium on carbon (0.20 g) in absolute ethanol (15 mL) was shaken under a hydrogen atmosphere (3 atm) for 4-24 hours, depending on substrate. The resulting reaction mixture was filtered through diatomaceous earth, and the filtrate was evaporated under reduced pressure. The residue was column chromatographed using silica gel (approximately 10 g) and elution with a solution of methylene chloride: methanol:ammonium hydroxide [8: 2: 0.2] or other appropriate solvent system to afford the corresponding 3-(pyrrolidin-2-ylmethyl)-1H-indole.
