Reaktionsschritte

Methyl 3-{4-[(4-{[(4-isopropyl-1,3-thiazol-2-yl)(3-methylbutyl)amino]methyl}benzyl)oxy]phenyl}propanoate (140 mg) was dissolved in a mixed solvent of methanol (2 mL) and tetrahydrofuran (2 mL), and 2N aqueous sodium hydroxide solution (2 mL) was added. The mixture was stirred at room temperature for 1 hr. The reaction mixture was poured into water, acidified with 1N aqueous hydrochloric acid solution, and extracted with ethyl acetate. The ethyl acetate layer was dried using Presep Dehydration tube (manufactured by Wako Pure Chemical Industries, Ltd.), and concentrated to give the title compound (120 mg, yield 88%) as a pale-yellow oil.
