実験手順

3-[(4-Methyl-cyclohexanecarbonyl)-(1-methyl-piperidin-3-ylmethyl)-amino]-5-phenyl-thiophene-2-carboxylic acid methyl ester (162 mg, 0.27 mmol) was dissolved in a mixture of THF:MeOH:H2O (3:2:1, 2.8 mL) and treated with LiOH.H2O (35 mg, 0.81 mmol). The solution was heated at 55° C. for 3 h. The solvents were removed and the residue was acidified using HCl to pH 4. The product was extracted with EtOAc and the organic layers were washed with brine, dried and evaporated to provide 3-[(4-Methyl-cyclohexanecarbonyl)-(1-methyl-piperidin-3-ylmethyl)-amino]-5-phenyl-thiophene-2-carboxylic acid (146 mg, 92% yield). 1H NMR (CDCl3, 400 MHz): 9.98 (br s, 1H), 7.80 (d, 1H), 7.62 (d, 1H), 7.48-7.24 (m, 9H), 5.20-5.05 (m, 2H), 4.35-3.95 (m, 3H), 3.00 (m, 1H), 2.85-2.52 (m, 2H), 2.15 (m, 1H), 1.82-1.18 (m, 12H), 0.78 (d, 3H), 0.68 (m, 2H).
