Procedure
67 mg (0.325 mmol) 3,3-dimethyl-7-nitro-2,3-dihydro-isoindol-1-one are dissolved in 50 ml of methanol and combined with 10 mg palladium on charcoal. The mixture is hydrogenated for 16 h at 4 bar H2 pressure and ambient temperature. Then the catalyst is filtered off and the solvent is eliminated in vacuo.
Workup
- filtrationThen the catalyst is filtered off
