Versuchsvorschrift

To a solution of ethyl 1,3-dihydro-2H-inden-2-ylideneacetate (302 mg, 1.49 mmol) in EtOAc (10 mL) was added 5% Pd/C (76 mg) and H2 was bubbled through the slurry for 20 h. The slurry was then filtered through Celite and the organic solution was concentrated in vacuo. Ethyl 2,3-dihydo-1H-inden-2-ylacetate (285 mg, 94%) was isolated as a colorless oil without purification.
