Procedure

Trifluoroacetic acid (3.42 g, 30 mmol) was added at 0° C. to a solution of (S)-tert-butyl 3-(1,3-dioxoisoin dolin-2-yloxy)pyrrolidin-1-carboxylate (3.32 g, 10 mmol) in CH2Cl2 (25 ml), and the whole was stirred at room temperature for 17 hours. The reaction was concentrated in vacuo and the residue was triturated with diethyl ether (100 ml) to give (S)-2-(pyrrolidin-3-yloxy)isoindoline-1,3-dione) trifluoroacetic acid salt (2.77 g, 80%) as a white solid.
