Procedure

5-(3-Fluoro-phenyl)-3-[isopropyl-(4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (25 mg, 0.060 mmol) was dissolved in a 4:1 mixture of dioxane:H2O (0.8 mL) and then LiOH 1N (0.3 ml, 0.300 mmol) was added. After 3 hours of stirring at room temperature, solvents were removed and then partitioned between 10 ml of H2O acidified to pH 4 and 10 ml of EtOAc. The organic layer was separated and the aqueous phase was washed twice with ethyl acetate (2×10 mL). The combined ethyl acetate layer was dried (Na2SO4), concentrated and the residue was purified by preparative chromatography (10% MeOH/CH2Cl2) to obtain 20 mg (83%) of 5-(3-Fluoro-phenyl)-3-[isopropyl-(4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid (Compound 5).
