Versuchsvorschrift

To a mixture of methyl 3-[4-({4-[[(4-phenyl-1,3-thiazol-2-yl)methyl](propyl)amino]benzyl}oxy)phenyl]propanoate (240 mg, 0.48 mmol), ethanol (5 mL) and tetrahydrofuran (5 mL) was added 2N aqueous sodium hydroxide solution (2 mL), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with water, neutralized with 1N hydrochloric acid, and extracted with ethyl acetate. The organic layer was concentrated and the residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:4-4:1 in volume ratio) to give the title compound (75 mg, yield 32%) as colorless prism crystals (recrystallized from acetone-heptane).
