Versuchsvorschrift

1,3,5-Tris[(6-amino-pyridin-2-yl)aminomethyl]-2,4,6-triethylbenzene (2b) (4.7 g, 8.9 mmol), 4,4-dimethoxy-2-butanone (26.3 mmol), and H3PO4 (50 mL) were held at 90° for 4 h and then stirred at room temperature for 2 h. The reaction mixture was poured into water (300 mL), neutralized, and extracted several times with chloroform. The collected organic layers were dried over MgSO4 and the solvent was removed under reduced pressure. The crude product was purified several times by column chromatography (silica gel, CHCl3/CH3OH, 7:1 to 2:1 v/v). Yield 23%. M.p. 207-208° C. 1H-NMR (400 MHz, CDCl3): δ=1.23 (t, 9H, J=7.5 Hz), 2.69 (s, 9H), 2.82 (q, 6H, J=7.5 Hz), 4.74 (br s, 3H), 4.82 (d, 3H, J=3.0 Hz), 6.58 (d, 3H, J=8.6 Hz), 7.04 (d, 3H, J=8.1 Hz), 7.72 (d, 3H, J=8.6 Hz), 7.79 (d, 3H, J=8.1 Hz). 13C NMR (100 MHz, CDCl3): δ=16.9, 23.1, 25.3, 40.6, 112.1, 115.2, 118.3, 132.9, 136.2, 136.9, 144.5, 156.7, 158.4, 161.3. HR-MS calcd for C42H44N6: 674.3719; found: 674.3714. Rf=0.89 (CHCl3/CH3OH 2:1 v/v).
