반응 단계

At 0° C., 705 mg (2.02 mmol) of N-{5-[4-(trifluoromethyl)phenyl]piperidin-3-yl}benzamide were initially charged in 70 ml of dichloromethane, and 321 mg (2.02 mmol) of morpholine-4-carbonyl chloride and 564 μl (4.04 mmol) of triethylamine were added. The mixture was slowly warmed to RT overnight. Water was added, and the reaction mixture was extracted. The organic phase was dried over magnesium sulphate and concentrated under reduced pressure. The residue was then purified by preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 960 mg (100% of theory)
