실험 절차

In a 5 mL microwave vial with septum cap, 3-[3-(2-chloro-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]-N-(2,6-difluorophenyl)-benzamide (Intermediate Example 1) (0.200 g, 0.433 mmol), 4-(1,4′-bipiperidin-1′-yl)-2,5-bis(methyloxy)aniline (0.166 g, 0.520 mmol) were taken up in iPrOH (3 mL) and concentrated HCl (4 drops) was added. The vial was sealed and heated in the microwave at 180° C. for 40 min. Reaction was complete by MS, it was cooled rt, neutralized with 7N ammonia in MeOH, and concentrated in vacuo. The resulting residue was taken up in DCM and purified by column chromatography using basic alumina. The desired combined fractions were concentrated and the resulting solid was triturated with DCM and hexane, filtered and air dried to give the title compound (0.130 g, 40%). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.23 (s, 1H), 9.41 (br. s., 1H), 8.50 (s, 1H), 8.33 (s, 1H), 8.24 (d, J=5.1 Hz, 1H), 8.05 (d, J=7.7 Hz, 1H), 7.83 (d, J=8.1 Hz, 1H), 7.73 (d, J=9.2 Hz, 1H), 7.60 (t, J=7.9 Hz, 1H), 7.43-7.50 (m, 1H), 7.36-7.42 (m, 1H), 7.34 (s, 1H), 7.20 (t, J=8.1 Hz, 2H), 6.94-7.00 (m, 1H), 6.66 (s, 1H), 6.50 (d, J=5.1 Hz, 1H), 3.76 (s, 3H), 3.64 (s, 3H), 3.43 (d, J=11.7 Hz, 2H), 2.51-2.58 (m, 2H), 2.26-2.35 (m, 1H), 1.77 (d, J=13.6 Hz, 2H), 1.53-1.64 (m, 2H), 1.48 (s, 4H), 1.38 (s, 2H). MS (M+H, ES+) 745.
