Methyl 4-{[2-oxodihydro-3(2H)-furanylidene]methyl}benzoate → Methyl 4-[(2-oxotetrahydro-3-furanyl)methyl]benzoate

Participants

Reaction Steps

20.00 g (0.09 mol) of methyl 4-([2-oxodihydro-3(2H)-furanylidene]methyl)benzoate from Ex. V are suspended in 240 ml of glacial acetic acid, 2.00 g of 10% palladium-carbon are added and the mixture is hydrogenated at atmospheric pressure for 4 hours. The reaction mixture is filtered through kieselguhr and the solvent is distilled off under reduced pressure.
