Reaction Steps

5-cyclohex-1-enyl-3-[(cis-4-fluoro-cyclohexyl)-(trans-4-methyl-cyclohexane-carbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (10 mg, 0.021) was dissolved in a mixture of THF, MeOH and H2O (3:2:1) (2 mL) and 1N LiOH (0.1 mL) was added. Rest of the procedure has been described earlier (example 3, step VIII). Pure 5-cyclohex-1-enyl-3-[(cis-4-fluoro-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid was obtained after chromatography over silica gel (5% MeOH in DCM as eluent) (5 mg, 51%).
