Participants

Reaction Steps

To a solution of methyl 3-[3-(2-{[2-(methyloxy)-4-(4-morpholinyl)phenyl]amino}-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]benzoate (65 mg, 0.12 mmol) in 2 mL THF was added 2,6-difluoroaniline (0.065 mL, 0.60 mmol) and a 1M solution of NaHMDS in THF (0.72 mL, 0.72 mmol). When LC/MS showed the reaction to be complete it was concentrated onto silica gel and purified by flash column chromatography to give 57 mg (75%) of the title compound. 1H NMR (400 MHz, DMSO-d6) δ 10.20 (s, 1H), 9.38 (s, 1H), 8.45 (s, 1H), 8.27 (s, 1H), 8.18 (d, J=5.2 Hz, 1H), 8.01 (d, J=7.6 Hz, 1H), 7.78 (d, J=7.2 Hz, 1H), 7.70 (d, J=8.8 Hz, 1H), 7.60-7.52 (m, 2H), 7.47-7.40 (m, 2H), 7.35-7.30 (m, 1H), 7.11-7.07 (m, 1H), 6.98-6.94 (m, 1H), 6.67 (s, 1H), 6.48-6.43 (m, 2H), 3.78 (s, 3H), 3.73-3.72 (m, 4H), 3.10-3.09 (m, 4H). MS (ESI) m/z=634 [M+H]+.
