Reaction Steps

To a solution of trans-4-{[4-(benzyloxy)-3-methylquinolin-2-yl]methoxy}cyclohexaneamine (300 mg) in dichloromethane (5 mL) were added 4-bromo butanoic acid chloride (0.11 mL) and triethylamine (0.15 mL) under ice-cooling, followed by stirring at the same temperature for 45 minutes. Water was added to the reaction mixture, followed by extraction with chloroform. The organic layer was washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was dissolved in THF, and 60% sodium hydride (50 mg) was added thereto. The reaction mixture was stirred at room temperature for 2 hours, followed by stirring for another 15 hours while heating it in an oil bath at 60° C. 60% sodium hydride (50 mg) was added to the reaction mixture, followed by stirring for 4 hours while heating it in an oil bath at 60° C. The reaction mixture was cooled to room temperature, and water was then added thereto, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and then the residue was purified by silica gel column chromatography (eluent: chloroform/methanol=100/0˜95/5). The solvent was evaporated under reduced pressure, and the residue was then dried under vacuum at room temperature to obtain 161 mg of 1-(trans-4-{[4-(benzyloxy)-3-methylquinolin-2-yl]methoxy}cyclohexyl)pyrrolidin-2-one as a yellow oily substance.
