Participants

Reaction Steps

Ethyl 3-{2-fluoro-4-[(4-{[[2-(4-fluorophenyl)ethyl](4-isopropyl-1,3-thiazol-2-yl)amino]methyl}benzyl)oxy]phenyl}-propanoate (485 mg) was dissolved in ethanol (5 mL), 2N aqueous sodium hydroxide solution (2 mL) was added, and the mixture was stirred at room temperature for 1 hr. The reaction mixture was diluted with water, neutralized with 1N hydrochloric acid, and extracted with ethyl acetate. The extract was dried using a Presep Dehydration tube (manufactured by Wako Pure Chemical Industries, Ltd.) and concentrated to give the title compound (354 mg, yield 75%) as colorless crystals.
