実験手順
This compound is prepared in a manner analogous to that described in Example 1, Step 2 for 1,5-di-pyridin-2-yl-pentane-1,3,5-trione, but instead the pyrrolidine-substituted triketone from Example 21 is used. Pure 4,4″-di-pyrrolidin-1-yl-1′H-[2,2′;6′,2″]terpyridin-4′-one can be obtained by recrystallisation from methanol in the form of an almost colourless solid. 1.81-2.05 (m, 8H); 3.17-3.33 (m, 8H); 6.32 (dd, 2H, J=5.7, 2.3 Hz); 6.84 (d, 2H, J=2.3 Hz); 6.90 (s, 2H); 8.19 (d, 2H, J=5.7 Hz). MS (EI pos., 70 eV), m/z=387 ([M+]), 359 (100); 358 (85); 330 (20); 28 (60).
