Versuchsvorschrift

To a solution of 3-[1-(4-tert-butyl-phenyl)-piperidin-4-yl]-propionic acid lithium salt (15 mg; 0.05 mmol, prepared in accordance with Example 146) 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 stirring 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 (6 mg; 0.011 mmol). The structure was confirmed using Protocol I-D. Calculated mass=561; observed mass=561; HPLC retention time=1.67 min.
