Versuchsvorschrift

Into a sealed tube were added 4-(4-chloro-7H-pyrrolo[2,3-d]pyrimidin-6-yl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (368 mg, 1.0 mmol), 3-(1H-imidazol-2-yl)-phenylamine (210 mg, 1.32 mmol), trifluoroacetic acid (847 μL, 11.0 mmol) and 1-butanol (10 mL). The above mixture was heated at 80° C. for 24 h. After that time, the mixture was concentrated in vacuo, and the residue was dissolved in DMSO for submission for MS-directed purification to obtain brown oil, which was purified again to give the title compound. 1H NMR (CD3OD, 400 MHz): δ=1.52 (s, 9H), 2.58 (brs, 2H), 3.68 (brs, 2H), 4.14 (brs, 2H), 6.30 (brs, 1H), 6.68 (s, 1H), 7.16 (s, 2H), 7,45 (t, 1H, J=8.0 Hz), 7.57-7.60 (m, 1H), 7.76-7.79 (m, 1H), 8.21 (t, 1H, J=1.6 Hz), 9.26 (s, 1H). MS (ES+): m/z 458.06 (100) [MH+]. HPLC: tR=2.17 min (ZQ2000, polar—5 min).
