Tetrahydrofuran → 3-[({4-[(1-{5-chloro-1-[3-(trifluoromethyl)phenyl]-1H-indol-2-yl}heptyl)amino]phenyl}carbonyl)amino]propanoic acid

Participants

Reaction Steps

To a mixture of ethyl 3-[({4-[(1-{5-chloro-1-[3-(trifluoromethyl)phenyl]-1H-indol-2-yl}heptyl)amino]phenyl}carbonyl)amino]propanoate (273 mg) synthesized above, tetrahydrofuran (5 mL) and ethanol (5 mL) was added 1N aqueous sodium hydroxide solution (5.00 mL), and the mixture was stirred at room temperature for 2 hr, and concentrated under reduced pressure. The residue was dissolved in water (10 mL), and 1N hydrochloric acid (5.00 mL) was added at 0° C. The resulting precipitate was collected by filtration to give the title object compound (253 mg, 97%) as a white solid.
