실험 절차
To a stirred solution of (S)-3-cyclohexyl-2-[2-oxo-4-(2-propyl-phenoxy)-2,5-dihydro-pyrrol-1-yl]-propionic acid methyl ester (440 mg, 0.001 mol) in tetrahydrofuran-water (3:1, 10 mL) was added lithium hydroxide (143 mg, 0.006 mol). The reaction mixture was stirred at 23° C. for 2 h. After this time, the mixture was concentrated and the reaction mixture was diluted with water. The reaction mixture was acidified with 2N hydrochloric acid, during which time precipitation occurred. The precipitate was removed by filtration, washed with cold water and dried in vacuo to obtain (S)-3-cyclohexyl-2-[2-oxo-4-(2-propyl-phenoxy)-2,5-dihydro-pyrrol-1-yl]-propionic acid (395 mg, 93%) as a yellow solid.
