Versuchsvorschrift

To a solution of methyl 3-(3-{2-[(3-{[2-(dimethylamino)ethyl]oxy}-2-methylphenyl)amino]-4-pyrimidinyl}imidazo[1,2-a]pyridin-2-yl)benzoate (60.0 mg, 0.115 mmol) and 2,6-difluoroaniline (0.0350 mL, 0.345 mmol) in THF (5 mL) was added sodium bis(trimethylsilyl)amide (0.46 mL, 0.460 mmol, 1.0 M solution in THF), and the reaction mixture was stirred for 5 min at rt. The mixture was quenched with saturated NaHCO3, diluted with DCM, and the organic layer was separated. The solvent was removed and the crude material was purified via silica gel chromatography to give 70 mg (98% yield) of the title compound. 1H NMR (400 MHz, DMSO-d6) δ 10.24 (s, 1H), 9.36 (d, J=6.6 Hz, 1H), 9.08 (s, 1H), 8.32 (s, 1H), 8.20 (d, J=5.3 Hz, 1H), 8.06 (d, J=7.9 Hz, 1H), 7.83 (d, J=7.7 Hz, 1H), 7.72 (d, J=9.0 Hz, 1H), 7.62 (t, J=7.8 Hz, 1H), 7.42 (t, 2H), 7.12-7.28 (m, J=8.0, 8.0 Hz, 3H), 7.03 (d, J=7.5 Hz, 1H), 6.87 (d, 2H), 6.48 (d, J=5.3 Hz, 1H), 4.07 (t, J=5.8 Hz, 2H), 2.66 (t, J=5.7 Hz, 2H), 2.22 (s, 6H), 2.07 (s, 3H).
