Reaction Steps
Ethyl 4-{3-[4-(3-bromo-1-phenylpropoxy)benzoyl]indol-1-yl}butanoate (1.97 g) obtained in Step 2 was dissolved in N,N-dimethylformamide (20 ml). 1-(2-Methoxyphenyl) piperazine (0.83 g) and potassium carbonate (0.75 g) were added to the resultant solution and stirred overnight at 60° C. After cooling, 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=2:1), obtaining 1.95 g of ethyl 4-{3-{4-{1-phenyl-3-[4-(2-methoxyphenyl)piperazin-1-yl]propoxy}benzoyl}indol-1-yl}butanoate as a colorless oily substance.
