Reaction Steps

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (728 mg, 3.80 mmol) was added to a solution of 3-{bis[4-(methoxymethoxy)phenyl]methyl}-1-(2-dimethylaminoethyl)indole-2-carboxylic acid (1.0 g, 1.90 mmol) obtained in Example 48 and propylamine (0.23 ml, 2.85 mmol) in 10 ml of methylene chloride, followed by stirring at room temperature for 3.5 hours. Water was added to the reaction solution followed by extraction with chloroform. The resulting organic layer was washed successively with 2N hydrochloric acid, a saturated aqueous solution of sodium bicarbonate, and a saturated aqueous solution of sodium chloride, and dried over magnesium sulfate, and the solvent was distilled off under reduced pressure to give 1.2 g (quantitative) of the title compound.
