Versuchsvorschrift

Ethyl 4-{3-[4-(4-methylphenylmethoxy)-3-(3-chloropropoxy)benzoyl]indol-1-yl}butanoate (2.59 g) obtained in Step 2 was dissolved in N,N-dimethylformamide (30 ml). 1-(2-Methoxyphenyl)piperazine (1.36 g), potassium carbonate (0.85 g), and potassium iodide (1.02 g) were added to the resultant solution and stirred overnight at 60° C. The reaction mixture was poured into water and extracted with ethyl acetate. The resultant extract was washed with brine and then dried. The solvent was distilled off. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=1:2), obtaining 2.47 g of ethyl 4-{3-{4-(4-methylphenylmethoxy)-3-{3-[4-(2-methoxyphenyl)piperazin-1-yl]propoxy}benzoyl}indol-1-yl}butanoate as a colorless oily substance.
