Procedure

To a solution of 4-[4-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazin-1-yl]-butyric acid lithium salt (17 mg; 0.05 mmol, prepared in accordance with Example 152) in tetrahydrofuran (0.5 mL) is added tetramethyl-O-(1H-benzotriazol-1-yl)uronium hexafluorophosphate (19 mg; 0.05 mmol) in dimethylformamide (0.25 mL) A solution of (4-nitro-3-trifluoromethyl-phenyl)-piperidin-4-yl-amine hydrochloride (16 mg; 0.05 mmol, prepared in accordance with Example 8) in dimethylformamide (0.25 mL) and diisopropylethyl amine (25 μL; 0.15 mmol) are then added and the reaction is stirred. After 3 hours at room temperature, aluminium oxide (90 active basic) is added and stiffing is continued for 40 minutes. The solids are removed by filtration and the filtrate is concentrated under high vacuum. The obtained residue is purified by preparative HPLC to afford the desired compound (16 mg; 0.0271 mmol). The structure was confirmed using Protocol I-D. Calculated mass=596; observed mass=596; HPLC retention time=1.42 min
