실험 절차

A solution of 3-[(4-methyl-cyclohexanecarbonyl)-piperidin-4-yl-amino]-5-phenyl-thiophene-2-carboxylic acid methyl ester (197 mg, 0.45 mmol) in CH2Cl2 (4.5 mL) was treated with K2CO3 (93 mg, 0.67 mmol) and cyanogen bromide (100 mg, 0.94 mmol). The reaction mixture was stirred at room temperature for 1 hour and heated at reflux for 18 h. The mixture was cooled at room temperature and filtered on celite. The filtrat was washed with AcOH (1N) and brine, dried (Na2SO4) and concentrated. The residue was purified by silica gel column chromatography using (2% MeOH/CH2Cl2) to provide 3-[(1-cyano-piperidin-4-yl)-(4-methyl cyclohexanecarbonyl)-amino]-5-phenyl-thiophene-2-carboxylic acid methyl ester (154 mg, 74% yield) as pale yellow foam.
