Procedure

A mixture of 2-chloro-N-{[2-(2,6-dioxo(3-piperidyl))-1,3-dioxoisoindolin-4-yl]methyl}acetamide (1.3 g, 3.57 mmol), sodium azide (0.3 g, 4.65 mmol) and sodium iodide (0.54 g, 3.57 mmol) in acetone (50 ml) was refluxed for 17 hours. The solvent was removed in vacuo and the residue was dissolved in EtOAc (60 ml). The EtOAc solution was washed with H2O (30 ml), brine (30 ml), and dried (MgSO4). The solvent was removed in vacuo to give 2-azido-N-{[2-(2,6-dioxo(3-piperidyl))-1,3-dioxoisoindolin-4-yl]methyl}acetamide (1.2 g, 90%) as a white solid: 1H NMR (CDCl3) δ d 8.48 (s, 1H), 7.84-7.68 (m, 3H), 7.51 (t, J=6.3 Hz, 1H), 5.04-4.97 (dd, J=4.7 and 11.8 Hz, 1H), 4.80 (d, J=6.5 Hz, 2H), 3.97 (s, 2H), 2.95-2.74 (m, 3H), 2.20-2.15 (m, 1H).
