실험 절차

To a solution of 1-(4-fluorophenyl)-1-oxo-3-(4-(trifluoromethyl)phenyl)-2-propylamine hydrochloride (600 mg, 1.73 mmol) and 4-oxo-4H-pyran-2-carboxylic acid (266 mg, 1.90 mmol) in N,N-dimethylformamide (10 ml) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (496 mg, 2.59 mmol), 1-hydroxy-1H-benzotriazole (396 mg, 2.59 mmol) and 1,8-diazabicyclo[5.4.0]-7-undecene (0.28 ml, 1.90 mmol) and the mixture was stirred overnight. To the reaction solution were added 1N aqueous hydrochloric acid solution (10 ml) and water (100 ml) and the mixture was extracted with ethyl acetate (50 ml×2). The extract was washed with 1N aqueous sodium hydroxide solution and saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate) and recrystallized from ethyl acetate-hexane to give N-(2-(4-fluorophenyl)-2-oxo-1-((4-(trifluoromethyl)phenyl)methyl)ethyl)-4-oxo-4H-pyran-2-carboxamide (570 mg, 76%).
