Procedure

4-[4-(4-Trifluoromethyl-phenyl)-piperazin-1-yl]-butyric acid lithium salt (35 mg; 0.11 mmol, prepared in accordance with Example 3), diisopropylethyl amine (174 μL; 1.0 mmol) and tetramethyl-O-(1H-benzotriazol-1-yl)uronium hexafluorophosphate (37 mg; 0.1 mmol) are diluted in a 2 to 1 mixture of dimethylformamide and tetrahydrofuran (1.5 mL) and the resulting solution is stirred for 5 minutes. A solution of (6-methyl-5-nitro-pyridin-2-yl)-piperidin-4-yl-amine hydrochloride (27 mg; 0.1 mmol, prepared in accordance with Example 100) in dimethylformamide (0.5 mL) is added and the reaction is then stirred for 90 minutes at room temperature. Following dilution with dichloromethane (10 mL), the organic layer is sequentially washed with water (5 mL), aq. sat. sodium hydrogen carbonate (3×5 mL), is dried over magnesium sulfate and concentrated under reduced pressure. The residue obtained is finally purified by preparative HPLC to deliver the desired product in pure form (42 mg; 0.08 mmol). The structure was confirmed using Protocol II-A. Calculated mass=535; observed mass=535; HPLC retention time=3.39 min.
