Versuchsvorschrift

A solution of N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (165 mg, 0.415 mmol) and butyraldehyde (50 mg, 0.69 mmol) in MeOH (4 mL) was heated at reflux for 30 minutes. The solution was allowed to cool to room temperature, 10% Pd/C (20 mg, 0.019 mmol) was added, and the mixture was stirred under hydrogen atmosphere (1 atm) at room temperature for 20 h. The mixture was filtered through Celite and the solvent from the filtrate was removed under reduced pressure. Purification of the crude material by column chromatography on silica gel (200:5:1 CH2Cl2/MeOH/NH4OH) afforded AMD9701 (16 mg, 8%) as a colourless foam. 1H NMR (CDCl3) δ0.87 (m, 3H), 1.24-1.49 (m, 4H), 1.68 (m, 1H), 2.02 (m, 2H), 2.26 (m, 1H), 2.56 (m, 2H), 2.79 (m, 2H), 3.68 (s, 2H), 3.73 (s, 2H), 3.97 (d, 1H, J=17 Hz), 4.08 (m, 1H), 4.17 (d, 1H, J=17 Hz), 7.18 (m, 5H), 7.35 (m, 2H), 7.42 (m, 1H), 7.58 (m, 2H), 8.69 (d, 1H, J=3.9 Hz); —C NMR (CDCl3) δ14.39, 20.84, 21.79, 23.77, 29.63, 32.57, 48.88, 49.53, 54.11, 60.58, 111.30, 119.11, 121.68, 122.04, 122.60, 128.47, 128.99, 135.09, 137.55, 138.30, 139.82, 147.33, 156.73, 157.89.
