실험 절차

In a 10 mL vial with septum cap, 5-[3-(2-chloro-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]-N-(2,6-difluorophenyl)-2-(ethyloxy)benzamide (Intermediate Example 6) (0.200 g, 0.395 mmol), 5-chloro-2-(methyloxy)-4-{4-[2-(methylsulfonyl)ethyl]-1-piperazinyl}aniline (0.165 g, 0.474 mmol) were taken up in iPrOH (3 mL) and pyridinium p-toluenesulfonate (0.238 g, 0.949 mmol) was added. The vial was sealed and heated to 80° C. overnight. When reaction was complete by MS, it was cooled to rt, neutralized with 7N ammonia in MeOH, absorbed onto silica gel and flash chromatographed. Fractions containing the desired product were concentrated and the resulting solid was triturated with diethyl ether, filtered and air dried to give the title compound (0.12 g, 0.15 mmol, 37%). 1H NMR (400 MHz, DMSO-d6) δ ppm 9.71 (s, 1H), 9.38 (dd, J=4.4, 1.1 Hz, 1H), 8.53 (s, 1H), 8.25 (d, J=5.3 Hz, 1H), 8.02 (d, J=0.4 Hz, 1H), 7.87 (s, 1H), 7.63-7.79 (m, 2H), 7.28-7.50 (m, 2H), 7.10-7.28 (m, 3H), 6.97 (t, J=6.9 Hz, 1H), 6.82 (s, 1H), 6.60 (d, J=5.2 Hz, 1H), 4.23 (q, J=6.7 Hz, 2H), 3.83 (s, 3H), 3.27-3.34 (m, 2H), 3.03 (s, 3H), 2.93-3.01 (m, 4H), 2.75 (t, J=6.6 Hz, 2H), 2.51-2.64 (m, 4H), 1.40 (t, J=6.8 Hz, 3H). MS (M+H, ES+) 817.
