実験手順
To a stirred solution of (S)-3-cyclohexyl-2-[4-(2,3-dimethyl-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-propionic acid methyl ester (850 mg, 0.002 mol) in tetrahydrofuran-water (3:1, 10 mL) was added lithium hydroxide (287 mg, 0.012 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-[4-(2,3-dimethyl-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-propionic acid (720 mg, 88%) as an off-white solid.
