Versuchsvorschrift

In a microwave vial with septum cap, 5-[3-(2-chloro-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]-N-(2,6-difluorophenyl)-2-(methyloxy)benzamide (Intermediate Example 2) (0.246 g, 0.5 mmol) and 5-ethyl-2-(methyloxy)-4-{4-[2-(methylsulfonyl)ethyl]-1-piperazinyl}aniline (0.171 g, 0.5 mmol) were taken up in 1,1,1-trifluoroethanol (3 mL) and 4M HCl in dioxane (0.25 mL, 1.0 mmol) 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 NH3 in MeOH, and concentrated in vacuo onto silica gel and flash chromatographed. The desired fractions were combined and concentrated and the resulting solid was triturated with diethyl ether, filtered and air dried to give the title compound (0.150 g, 0.19 mmol, 38%). 1H NMR (400 MHz, DMSO-d6) δ ppm 9.78 (s, 1H), 9.34 (dd, J=3.1, 2.2 Hz, 1H), 8.49 (s, 1H), 8.24 (d, J=5.1 Hz, 1H), 8.11 (d, J=1.3 Hz, 1H), 7.78 (dd, J=8.9, 1.4 Hz, 1H), 7.70 (d, J=9.0 Hz, 1H), 7.54 (s, 1H), 7.33-7.50 (m, 2H), 7.28 (d, J=8.8 Hz, 1H), 7.18 (t, J=8.1 Hz, 2H), 6.94 (t, J=6.6 Hz, 1H), 6.83 (s, 1H), 6.57 (d, J=4.9 Hz, 1H), 3.98 (s, 3H), 3.80 (s, 3H), 3.28-3.40 (m, 2H), 3.06 (s, 3 H), 2.82-2.92 (m, 4H), 2.77 (t, J=6.5 Hz, 2H), 2.50-2.69 (m, 6H), 1.08 (q, J=7.0 Hz, 3H).
