3-[4-(4-Methylphenylmethoxy)-3-(3-chloropropoxy) benzoyl]-1-(phenylsulfonyl)indole (0.44 g) obtained in Step 2 was dissolved in N,N-dimethylformamide (5 ml). 1-(2-Methoxyphenyl)piperazine (0.20 g), potassium carbonate (0.14 g), and potassium iodide (0.38 g) were added to the resultant solution and the mixture was stirred overnight at 60° C. Water was added to the reaction mixture, followed by extraction 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=1:3), obtaining 0.29 g of 3-{4-(4-methylphenylmethoxy)-3-{3-[4-(2-methoxyphenyl)piperazin-1-yl]propoxy}benzoyl}-1-(phenylsulfonyl)indole (0.29 g) as a light yellow oily substance.
