Versuchsvorschrift

To a suspension of 3,5-dichloro-isonicotinoyl chloride (0.34 mmol) in THF (3 mL) at 0° C. was added a solution of N1-(1H-benzoimidazol-2-ylmethyl)-N1-(5,6,7,8-tetrahydro-quinolin-8-yl)-ethane-1,2-diamine (0.100 g, 0.312 mmol) in dichloromethane (3 mL), THF (1 mL) and Et3N (0.087 mL). After stirring at 0° C. for 5 min., the mixture was warmed to room temperature and stirred for 2.5 h. The solvents were evaporated and the residue was taken into saturated aqueous NaHCO3 (30 mL). The mixture was extracted with chloroform (3×20 mL). The extracts were dried over Na2SO4 and concentrated. Purification of the crude material by column chromatography on silica gel (200:1:1 CH2Cl2—CH3OH—NH4OH) provided 55 mg (44%) of COMPOUND 152 as a pale yellow solid 1H NMR (CDCl3) δ 1.55-1.70 (m, 1H), 1.78-1.85 (m, 1H), 2.03 (m, 1H), 2.29 (m, 1H), 2.66-2.82 (m, 3H), 3.20 (d, J=13.5 Hz, 1H), 3.39 (m, 1H), 3.55 (m, 1H), 3.90 (dd, J=10.8 Hz, 5.7 Hz, 1H), 4.12 (d, J=16.7 Hz, 1H), 4.30 (d, J=16.7 Hz, 1H), 6.99 (dd, 1H, J=7.8 Hz, 4.8 Hz, 1H), 7.15-7.21 (m, 2H), 7.27 (m, 1H), 7.41 (d, J=7.8 Hz, 1H), 7.54 (d, J=4.2 Hz, 1H), 7.63 (d, J=4.2 Hz, 1H), 8.40 (m, 1H), 8.56 (s, 2 H); 13C NMR (CDCl3) δ 21.79, 23.08, 29.32, 38.68, 48.54, 49.25, 61.63, 119.35, 122.24, 122.69, 123.19, 129.64, 133.76, 135.76, 138.70, 143.50, 144.39, 146.46, 148.03, 154.85, 157.38, 162.22; ES-MS m/z 496 (M+H).
