实验过程

400 mg (0.89 mmol) trans-4-{4-[Methyl-(4-trifluoromethyl-benzenesulfonyl)-amino]-cyclohexyloxy}-butyrimidic acid ethyl ester were suspended in 10 ml water and heated to 100° C. for 2.5 h. EtOAc was added, and the inorganic phase was extracted with EtOAc. The combined organic phases were dried over Na2SO4 and evaporated to give 355 mg (89%) trans-4-{4-[Methyl-(4-trifluoromethyl-benzenesulfonyl)-amino]-cyclohexyloxy}-butyric acid ethyl ester as yellow oil, MS: 452 (MH+).
