2.5 g (15.7 mmol) of 3-acetyl-1H-indole are dissolved in 100 ml of dimethylformamide, and 0.41 g (15.7 mmol) of sodium hydride and 4.0 g (16 mmol) of N-(2-bromo-ethyl)-phthalimide are added. The reaction mixture is stirred for 14 h at RT and for 3 h at 50°. 20 ml of water are added and the product is isolated by filtration. After drying at 50° under HV, N-[2-(3-acetyl-1H-indol-1-yl)-ethyl]-1H-isoindole-1,3(2H)-dione is obtained; 1H-NMR (CDCl3): 2.5 (3H,s), 4.1 (2H,t), 4.45 (2H,t), 7.2-7.9 (8H,m), 8.35 (1H n).
