実験手順
A solution of 197 mg (0.841 mmol) of 4-(4-nitro-phenyl)-piperidine-2,6-dione (as prepared in the previous step) in methyl alcohol (MeOH) (15 mL) was hydrogenated over 10% Pd/C at 20 psi for 5 h at RT. The mixture was filtered through Celite, the filter cake was washed with MeOH, and the solvents were evaporated in vacuo to afford 106 mg (62%) of the title compound as an off-white solid: Mass spectrum (ESI, m/z): Calcd. for C11H12N2O2, 205.1 (M+H). found 205.1.
