Procedure

To a stirred suspension 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 3) in tetrahydrofuran (1.0 mL) is added tetramethyl-O-(1H-benzotriazol-1-yl)uronium hexafluorophosphate (19 mg; 0.05 mmol) in dimethylformamide (0.5 mL). 15 minutes later, a solution of 4-(piperidin-4-ylamino)-2-trifluoromethyl-benzonitrile hydrochloride (15 mg; 0.05 mmol, prepared in accordance with Example 155) in dimethylformamide (0.5 mL) and diisopropylethyl amine (25 μL; 0.15 mmol) is added. After 2 hours at room temperature, aluminium oxide (90 active basic) is added and stiffing is continued. 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 (9 mg; 0.016 mmol). The structure was confirmed using Protocol I-D. Calculated mass=569; observed mass=569; HPLC retention time=1.48 min.
