Procedure

A suspension of 37 g (0.116 mol) of 7-(4-benzyl-piperazin-1-yl)-naphthalen-1-ol and 15 g (0.134 mol) of potassium tert.butoxide in 150 ml of dimethylformamide is stirred for 30 minutes at ambient temperature and then slowly combined with 11 ml (0.135 mol) of ethyl iodide. It is then stirred for 14 hours at ambient temperature. Then the reaction mixture is concentrated by evaporation and the residue is extracted with dichloromethane and water. It is filtered through aluminium oxide, dried over sodium sulphate and the solvent is distilled off. The residue is recrystallised from isopropanol.
