Reaction Conditions

Reaction Steps

Ammonium formate (419 mg) and 10% Pd/C (84 mg) were added to an ethyl acetate/MeOH (4 ml/4 ml) solution containing benzyl 3-((tert-butoxycarbonyl)amino)-4-(1,3-dioxoisoindolin-2-yl)piperidin-1-carboxylate (419 mg) obtained in the 1st step, followed by stirring at 60° C. for 1 hour. The reaction solution was cooled to room temperature and insoluble matter was removed through Celite. Filter cake was washed with ethyl acetate and water. Subsequently, the filtrate was mixed with wash liquid and sodium chloride was added to the mixture. The organic layers were separated and washed with saturated saline. The organic layers were dried over anhydrous sodium sulfate and the solvent was distilled away under reduced pressure. A white solid of tert-butyl (4-(1,3-dioxoisoindolin-2-yl)piperidin-3-yl)carbamate (280 mg) was thus obtained.
