Versuchsvorschrift
A mixture of 3-isopropylidene-4-methoxy-1,3-dihydro-indol-2-one (700 mg, 3.4 mmol) and 5% palladium on carbon (88 mg) in ethanol (25 mL) is hydrogenated at 60 psi overnight. Filtration and removal of the solvent in vacuo provided 560 mg (79%) of 3-isopropyl-4-methoxy-1,3-dihydro-indol-2-one. MS (ESI+) 206.
