실험 절차

A solution of 3-[(4-methyl-cyclohexanecarbonyl)-piperidin-4-yl-amino]-5-phenyl-thiophene-2-carboxylic acid methyl ester (145 mg, 0.33 mmol) in CH2Cl2 (3.3 mL) was treated with Et3N (69 mL, 0.49 mmol) and methyl isocyanate (28.2 mg, 0.49 mmol). After stirring at room temperature for 18 h, starting material remained. Methyl isocyanate (28.2 mg, 0.49 mmol) was added to the reaction that was stirred for another 4 h. The solvent was evaporated and the residue was dissolved in EtOAc, washed with HCl (0.1 M) and brine, dried (Na2SO4) and concentrated. The residue was purified by silica gel column chromatography using (5% MeOH/CH2Cl2) to provide 3-[(1-Methylcarbamoyl-piperidin-4-yl)-(4-methyl-cyclohexanecarbonyl)-amino]-5-phenyl-thiophene-2-carboxylic acid methyl ester (142 mg, 87% yield). 1H NMR (CDCl3, 400 MHz): 7.65 (m, 2H), 7.45 (m, 3H), 7.00 (s, 1H), 4.78 (m, 1H), 4.35 (q, 1H), 4.05 (dd, 1H), 3.90 (m, 1H), 3.85 (s, 3H), 2.85 (m, 2H), 2.75 (d, 3H), 1.95 (m, 2H), 1.80 (m, 1H), 1.70-1.55 (m, 5H), 1.50-1.25 (m, 3H), 1.10 (m, 1H), 0.78 (d, 3H), 0.75-0.58 (m, 2H).
