Reaction Steps

Ethyl 4-{3-{4-{1-phenyl-3-[4-(2-methoxyphenyl) piperazin-1-yl]propoxy}benzoyl}indol-1-yl}butanoate (1.89 g) obtained in Step 3 was dissolved in ethanol (20 ml). Potassium hydroxide (0.80 g) was added to the resultant solution and stirred for 3 hours at room temperature. After adding acetic acid (2 ml) to the reaction mixture, the solvent was distilled off. Water was added thereto, followed by extraction with ethyl acetate. The resultant extract was washed with brine and dried. The solvent was distilled off. The residue was purified by silica gel column chromatography (methylene chloride: methanol=40:1), obtaining 1.68 g of 4-{3-{4-{1-phenyl-3-[4-(2-methoxyphenyl)piperazin-1-yl] propoxy}benzoyl}indol-1-yl}butanoic acid as amorphous powder.
