Reaction Steps

A mixture of 60.5 parts of 1-(3-chloropropyl)-1,3-dihydro-3-(1-methylethenyl)-2H-benzimidazol-2-one, 31.68 parts of 1-(phenylmethyl)piperazine, 21.2 parts of sodium carbonate, 0.1 parts of potassium iodide and 400 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, yielding 1,3-dihydro-1-(1-methylethenyl)-3-{3-[4-(phenylmethyl)-1-piperazinyl]propyl}-2H-benzimidazol-2-one as a residue.
