Ethyl (5-methoxy-2,3-dihydro-1H-inden-1-ylidene)ethanoate → HCID 10263432, compound

Participants

Reaction Steps

Into a 50-mL round-bottom flask, was placed ethyl 2-(5-methoxy-2,3-dihydro-1H-inden-1-ylidene)acetate (500 mg, 2.15 mmol, 1.00 equiv), methanol (3 mL), Palladium carbon (500 mg). To the mixture hydrogen was introduced in. The resulting solution was stirred overnight at room temperature. The solids were filtered out. The mixture was dried over anhydrous sodium sulfate. The solids were filtered out. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (15:85). This resulted in 300 mg (59%) of ethyl 2-(5-methoxy-2,3-dihydro-1H-inden-1-yl)acetate as colorless oil.
