実験手順

5-iodo-1-(3-piperidin-1-yl-propyl)-1H-pyridin-2-one (18) (0.096 g, 0.28 mmol), 1-phenyl-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-benzoimidazole (0.081 g, 0.25 mmol), palladium(II) acetate (0.003 g, 0.013 mmol), triphenylphosphine (0.010 g, 0.038 mmol) and sodium carbonate (0,080 g, 0.75 mmol) were stirred in 1.6 mL of a 3:1 mixture of dioxane/water. The mixture was degassed 3x by alternating vacuum and an argon atmosphere. The reaction was heated to 80° C. for 18 h, cooled and diluted with water. The aqueous phase was extracted 3x with EtOAc and the resulting organic phase was dried over Na2SO4, filtered and concentrated. Purification by flash column chromatography (eluted with 85:15 CH2Cl2 /MeOH) afforded 0.073 g 5-(1-phenyl-1H-benzoimidazol-5-yl)-1-(3-piperidin-1-yl-propyl)-1H-pyridin-2-one (19) (71% yield). 1H NMR (CDC13) o 9.60 (s, 1H), 7.90 (d, J=1.3 Hz, 1H), 7.74-7.67 (m, 2H), 7.64-7.48 (m, 6H), 7.39 (dd, J=2.5, 9.5 Hz, 1H), 6.68 (d, J=9.5 Hz, 1H), 4.13 (t, J=6.5 Hz, 2H), 2.42 (bs, 6H), 2.10 (t, J=6.5 Hz, 2H), 1.64 (m, 4H), 1.46 (m, 2H).
