3-(4-Nitro-1-oxoisoindolin-2-yl)-2,6-dioxo-5-acetoxypiperidine → 3-(4-Amino-1-oxoisoindolin-2-yl)-2,6-dioxo-5-acetoxypiperidine

Participants

Reaction Steps

A solution of 3-(4-nitro-1-oxoisoindolin-2-yl)-2,6-dioxo-5-acetoxypiperidine (0.9 g, 3.1 mmol) and Pd/C (10%, 0.1 g) in methanol (100 mL) is shaken under hydrogen (50-60 psi) for 3 hours. The suspension is filtered through a pad of Celite and washed with methanol to give 3-(4-amino-1-oxoisoindolin-2-yl)-2,6-dioxo-5-acetoxypiperidine which is further purified by column chromatography.
