Procedure
11 G. of 1-(8-chloro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-yl)piperazine are heated together with 15.5 g. of potassium carbonate, 0.5 g. of sodium iodide, 11 g. of N-(beta-chloroethyl)-pyrrolidinone and 150 ml. of toluene under reflux conditions over a period of 12 hours. The reaction mixture is evaporated under reduced pressure. The residue is dispersed between water and ether and the ethereal phase is dried over sodium sulfate and evaporated, whereby there is obtained 1-{-2-[4-(8-chloro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin10-yl)-1-piperazinyl]-ethyl}-2-pyrrolidinone, having a melting point of 153°-164°. The maleate melts at 179°-180°.
