Versuchsvorschrift

A suspension of N-[(3-aminophenyl)methyl]-2,2,2-trifluoroacetamide (73 mg, 0.34 mmol) and N-{3-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]phenyl}-2-(3-thienyl)acetamide (120 mg, 0.27 mmol) in i-PrOH (4 mL) was acidified with 3 drops of 12 N HCl and stirred at 80° C. overnight. After 16 h, the reaction mixture was diluted with DCM, washed with saturated aqueous NaHCO3, dried over Na2SO4, and adsorbed onto silica gel. The crude product was purified by column chromatography to generate the title compound in 53% yield. 1H NMR (400 MHz, d6-DMSO) δ 10.28 (s, 1H), 9.98 (t, 1H), 9.63 (s, 1H), 8.83 (d, J=6.9 Hz, 1H), 8.52 (d, J=9.0 Hz, 1H), 8.24 (d, J=5.1 Hz, 1H), 7.90 (s, 1H), 7.63 (s, 1H), 7.75 (d, J=9.0 Hz, 1H), 7.71 (s, 1H), 7.67 (d, J=8.2 Hz, 1H), 7.47-7.49 (m, 2H), 7.42 (t, J=7.9 Hz, 1H), 7.32 (d, J=2.2 Hz, 1H), 7.26 (d, J=9.1 Hz, 1H), 7.22 (d, J=7.9 Hz, 1H), 7.08-7.13 (m, 2H), 6.85 (d, J=7.7 Hz, 1H), 6.51 (d, J=5.1 Hz, 1H), 4.35 (d, J=5.9 Hz, 2H), 3.66 (s, 2H).
