Versuchsvorschrift

To a solution of (2-amino-5-chlorophenyl)(phenyl)methanone (693 mg, 3.0 mmol) in ethanol (10 ml) was added 4-(1-(3-oxobutanoyl)piperidin-4-yl)benzamide (893 mg, 3.1 mmol) followed by ytterbium triflate (186 mg, 0.3 mmol). The mixture was heated at 82° C. for 12 hours. The reaction mixture was cooled to room temperature, and the white powder thus obtained was filtered off, washed with ethanol, ethyl acetate, and finally ether to provide 4-(1-(6-chloro-2-methyl-4-phenylquinoline-3-carbonyl)piperidin-4-yl)benzamide (1.1 g, 76%) as a free flowing white powder. 1H NMR (DMSO-d6, 400 MHz) 3:1 Rotameric forms complicates spectrum, the major rotamer is described; δ 8.09 (d, 1H, J=8.9 Hz); 7.9 (bs, NH, 1H); 7.8 (m, 3H); 7.7-7.5 (m, 6H); 7.25 (bs, NH, 1H); 6.8 (app d, 2H); 4.5 (d, 1H, J=12.9 Hz); 3.4-3.3 (m, 1H); 3.38 (s, 3H); 3.13 (app t, 1H, J=12.9 Hz); 2.8-2.4 (m, 2H); 2.5 (s, 3H); 0.72 (m, 1H); 0.54 (m, 1H). LC MS (CI) shows M+H 484.
