Versuchsvorschrift

4-(1,3-Dihydro-2H-benzimidazol-2-on-1-yl)piperidine (49 mg) was dissolved in methyl ethyl ketone (1.8 ml), added with the 1-bromo-3-[2-(4-diethylcarbamoylbenzyl)-phenoxy]propane (91 mg) obtained in Reference Example 1 and triethylamine (47 μl) and stirred at room temperature for 17 hours. The reaction mixture was added with water (2 ml) and extracted twice with ethyl acetate (2 ml). The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: dichloromethane:methanol=20:1) to obtain 49.7 mg of the title compound. Yield: 41%.
