At 0° C., 100 mg (0.27 mmol) of N-{5-[4-(trifluoromethoxy)phenyl]piperidin-3-yl}benzamide were initially charged in 1.5 ml of dichloromethane, and 82 mg (0.55 mmol) of morpholine-4-carbonyl chloride and 58 μl (0.412 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: 118 mg (90% of theory)
