1.2 9 of 2-(2-chloroethoxy)-2,3-dihydro-1H-benz[de]isoquinoline-1,3-dione ("D") [obtainable by reaction of N-hydroxy-2,3-dihydro-1H-benz[de]isoquinoline-1,3-dione with 1,2-dichloroethane to give 2-(2-chloroethoxy)-2,3-dihydro-1H-benz[de]isoquinoline-1,3-dione] and 1.0 g of 4-(5-fluoroindol-3-yl)piperidine [obtainable by reaction of N-BOC-4-chloropiperidine with 5-fluoroindole and subsequent removal of the protective group] are dissolved in 200 ml of acetonitrile and the solution is stirred at room temperature for 8 hours. Customary working up gives 2-[2-(4-(5-fluoro-3-indolyl)piperidino)ethoxy]-2,3-dihydro-1H-benz[de]isoquinoline-1,3-dione, hydrochloride hydrate, m.p. 271°.
