A solution of 1.00 g (0.005 mol) of rac-cis-2,3,3a,4,5,9b-Hexahydro-6-methoxy-1H-benzo[e]indole in 60 ml of ethyl methyl ketone was treated with 0.86 g (0.006 mol) of potassium carbonate, 0.29 g (0.002 mol) of sodium iodide and 1.50 g (0.005 mol) of N-(5-bromopentyl)phthalimide. The mixture was heated under reflux for 24 hours and, after cooling, treated with water. The mixture was extracted with ethyl acetate, the extracts were dried with sodium sulphate and the solvent was distilled off in a vacuum. Chromatography over silica gel with methylene chloride/methanol 20:1 gave 1.97 g (95%) of rac-N-[5-(cis-1,2,3a, 4,5,9b-hexahydro-6-methoxy-3H-benzo[e]indol-3-yl)pentyl]phthalimide.
