실험 절차

A solution of 3-cyclopentyl-2-(3,4-dichlorophenyl)-propionic acid (prepared as in Example 1, 100 mg, 0.34 mmol), benzotriazol-1-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate (166 mg, 0.38 mmol), triethylamine (0.096 mL, 0.68 mmol), and 2-aminoquinoline (75 mg, 0.52 mmol) in dry N,N-dimethylformamide (2 mL) was stirred at 25° C. for 14 h. The reaction mixture was then diluted with water and ethyl acetate, and the layers were separated. The organic layer was sequentially washed with a saturated aqueous sodium bicarbonate solution, water, and a saturated aqueous sodium chloride solution. The organic layer was dried over magnesium sulfate, filtered, and concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 4/1 hexanes/ethyl acetate) afforded 3-cyclopentyl-2-(3,4-dichloro-phenyl)-N-quinolin-2-yl-propionamide (70 mg, 50%) as a white foam: mp 172-173° C.; EI-HRMS m/e calcd for C23H22Cl2N2O (M+) 412.1109, found 412.1108.
