Versuchsvorschrift
Methyl 3-oxo-2,3-dihydro-1H-indene-5-carboxylate (3.5 g, 18.421 mmol, 1.0 eq.) was dissolved in MeOH (40 ml) and cooled to 0° C.; NaBH4 (749 mg, 20.263 mmol, 1.1 eq.) was added in portions and the mixture was stirred for 3 hours at RT. After monitoring by TLC, the reaction mixture was concentrated to dryness under reduced pressure, and the residue was taken up in water (100 ml) and extracted with dichloromethane (2×100 ml). The combined org. phases were dried over sodium sulfate, concentrated under reduced pressure and used in the next stage without being purified further. Yield: 92% (3.2 g, 16.66 mmol)
