実験手順

A mixture of 5-[3-(2-chloro-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]-N-(2,6-difluorophenyl)-2-(ethyloxy)benzamide (Intermediate Example 6) (0.10 g, 0.198 mmol), 5-ethyl-2-(ethyloxy)-4-{4-[4-(methylsulfonyl)-1-piperazinyl]-1-piperidinyl}aniline (Example 204, Step E) (0.081 g, 0.198 mmol) and HCl (4N,1,4-Dioxane, 0.099 mL, 0.395 mmol) in Trifluoroethanol (8 mL) was heated at 170° C. for 40 min in the microwave. The reaction was quenched with 7N NH3 in MeOH and then concentrated to dryness. The residue was then dissolved in DCM and concentrated onto silica gel. Purification by flash column chromatography followed by recrystallization from DCM and EtOH afforded the title compound N-(2,6-difluorophenyl)-5-(3-{2-[(5-ethyl-2-(ethyloxy)-4-{4-[4-(methylsulfonyl)-1-piperazinyl]-1-piperidinyl}phenyl)amino]-4-pyrimidinyl}imidazo[1,2-a]pyridin-2-yl)-2-(ethyloxy)benzamide (0.112 g, 61%) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 9.75 (s, 1H), 9.26-9.40 (m, 1H), 8.40 (s, 1H), 8.27 (d, J=5.22 Hz, 1H), 8.07 (d, J=2.02 Hz, 1H), 7.77 (dd, J=8.57, 2.25 Hz, 1H), 7.71 (d, J=8.98 Hz, 1H), 7.59 (s, 1H), 7.33-7.51 (m, 2H), 7.27 (d, J=8.61 Hz, 1H), 7.15-7.24 (m, 2H), 6.88-6.98 (m, 1H), 6.81 (s, 1H), 6.60 (d, J=5.22 Hz, 1H), 4.21-4.34 (m, 2H), 4.07 (q, J=6.93 Hz, 2H), 3.07-3.17 (m, 4H), 2.97-3.06 (m, 2H), 2.87 (s, 3H), 2.59-2.77 (m, 6H), 2.55 (q, J=7.45 Hz, 2H), 2.37-2.46 (m, 1H), 1.79-1.90 (m, 2H), 1.53-1.68 (m, 2H), 1.44 (t, J=6.92 Hz, 3H), 1.26 (t, J=6.97 Hz, 3H), 1.10 (t, J=7.51 Hz, 3H). MS (M-2H, ES−) 878.
