実験手順

A mixture of 4.94 parts of 1-(4-chlorobutyl)-1,3-dihydro-2H-benzimidazol-2-one, 5.76 parts of 1-[bis(4-fluorophenyl)methyl]piperazine, 5.3 parts of sodium carbonate, 0.2 parts of potassium iodide and 200 parts of 4-methyl-2-pentanone is stirred and refluxed for 20 hours with water-separator. The reaction mixture is cooled, water is added and the layers are separated. The organic phase is dried, filtered and evaporated. The residue is crystallized from ethanol. The product is filtered off and dried, yielding 1-[4-{4-[bis(4-fluorophenyl)methyl]-1-piperazinyl}butyl]-1,3-dihydro-2H-benzimidazol-2-one dihydrochloride.hydrate; mp. 184.4° C.
