A solution of 3-(2-bromo-ethyl)-1H-indole (4.48 g, 20 mmol) and isoindole (4.76 g, 40 mmol) in abs. dioxane (50 ml) was stirred at 80° C. for 6 h. The solvent was then removed i. vac., CHCl3 (100 ml) was added to the residue and the mixture was washed twice with water. The organic phase was dried over Na2SO4 and concentrated i. vac. and the residue which remained was purified by flash chromatography with CHCl3/MeOH (20:1).
