Procedure
To a stirred solution of 5-cyclohex-1-enyl-3-[(1-isobutyryl-piperidin-4-yl)-(trans-4-methyl cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (50 mg, 0.10 mmol) in THF:H2O:MeOH (3:1:2) (3 mL), was added LiOH in water (1N) (0.3 mL, 0.3 mmol). The reaction mixture was stirred at 70° C. for 5 h. The mixture was concentrated under reduced pressure on a rotary evaporator and the residue was treated with a solution of 0.1 N HCl and extracted in EtOAc. The EtOAc layer was dried over Na2SO4. Filtration and removal of the solvent under reduced pressure on a rotary evaporator followed by HPLC purification afforded 5-cyclohex-1-enyl-3-[(1-isobutyryl-piperidin-4-yl)-(trans-4-methyl cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid (30.0 mg, 61%) as a foam.
