A mixture of compound of Description 6 [5-methoxy-3-(piperidin-3-ylmethyl)-1H-indole] (2 g; 0.0082 mol), sodium bicarbonate (0.68 g; 0.0082 mol), KI (0.087 g; 0.00053 mol) and 2-(3-chloropropyl)-2-(4-fluorophenyl)-1,3-dioxolane [2.2 g (1,8 ml); 0.009 mol] in dry dimethylformamide (25 ml) and tetrahydrofuran (25 ml), was heated under reflux for 5 hours. After evaporation under vacuum, the residue was flash chromatographed on silica gel using as eluent methylene chloride/methanol/ammonia (95/5/0.5) and the desired compound was obtained. A solution of the compound in ethanol was saturated with gaseous hydrogen chloride, a solid was precipitated. The title compound hydrochloride was collected by filtration.
