3-[3-(2-Chloro-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]-N-(2,6-difluorophenyl)-benzamide (Intermediate Example 1) (108 mg, 0.23 mmol), 2-(methyloxy)-4-[2-(4-methyl-1-piperazinyl)ethyl]aniline (Example 131, step D) (52 mg, 0.21 mmol), and p-toluenesulfonic acid (107 mg, 0.56 mmol) were weighed into a 10 mL microwave vial. 5 mL of iPrOH was added and the mixture was heated in the microwave to 180° C. for 17 min. The mixture was transferred to a 50 mL round bottom and neutralized with 1 mL of 0.5 N sodium methoxide. The solvent was rotovaped down. The residue was taken up in 10 mL of DCM. 1 g of silica gel was added. The solvent was rotovaped down and the pre-adsorbed solids were purified by flash chromatography to give the title compound (61 mg, 0.09 mmol, 37%). 1H NMR (400 MHz, CDCl3) δ ppm 9.47 (d, J=6.97 Hz, 1H), 8.27-8.31 (m, 2H), 8.26 (d, J=5.50 Hz, 1H), 7.98-8.06 (m, 2H), 7.81 (d, J=8.07 Hz, 1H), 7.71 (s, 1H), 7.67 (d, J=8.80 Hz, 1H), 7.51 (t, J=7.70 Hz, 1H), 7.32-7.40 (m, 1H), 7.18-7.26 (m, 1H), 6.98 (t, J=8.25 Hz, 2H), 6.89 (t, J=6.78 Hz, 1H), 6.78-6.84 (m, 2H), 6.60 (d, J=5.50 Hz, 1H), 3.93 (s, 3H), 2.76-2.85 (m, 2H), 2.43-2.75 (m, 10H), 2.32 (s, 3H). MS (ESI): 675 [M+H]+.
