Procedure

The mixture of 4-{2-[2-(2-Azido-ethyl)-1-benzhydryl-5-chloro-1H-indol-3-yl]-ethoxy}-benzaldehyde (1.29 g, 2.41 mmole, 1.0 equiv.), 2,4-thiazolidine dione (0.41 g, 3.13 mmole, 1.3 equiv.) and piperidine (0.12 ml, 1.21 mmole, 0.5 equiv.) in EtOH (125 ml) was refluxed overnight. EtOH was removed on vacuo. The residue was diluted in EtOAc and washed with water, then brine. The organic layer was dried over MgSO4 and concentrated, and the residue was chromatographed with 30-35% EtOAc/hexane to obtain 5-(4-{2-[2-(2-Azido-ethyl)-1-benzhydryl-5-chloro-1H-indol-3-yl]-ethoxy}-benzylidene)-thiazolidine-2,4-dione (1.33 g, 87%).
