実験手順

To 5-[3-(2-chloro-4-pyrimidinyl)imidazo[1,2-a]pyridin-2-yl]-N-(2,6-difluorophenyl)-2-[(1-methylethyl)oxy]benzamide (Intermediate Example 7) (0.13 g, 0.25 mmol) and 2-(ethyloxy)-5-methyl-4-{4-[2-(methylsulfonyl)ethyl]-1-piperidinyl}aniline (0.087 g, 0.25 mmol) in 2,2,2-trifluoroethanol (1.5 mL) was added HCl (4M in dioxane) (0.13 mL, 0.50 mmol). The reaction was heated to 180° C. for 40 min in a microwave. The reaction was determined to be complete by HPLC. The reaction mixture was quenched with saturated NaHCO3 and sequentially extracted with DCM and EtOAc. The organic layer was dried (MgSO4), filtered, and rotovapped down. Purification by flash chromatography provided the title compound (0.05 g, 0.06 mmol, 24%). 1H NMR (400 MHz, DMSO-d6) δ 9.72 (s, 1H), 9.36 (d, J=5.9 Hz, 1H), 8.37 (s, 1H), 8.28 (d, J=4.9 Hz, 1H), 8.09 (br. s., 1H), 7.74 (dd, J=14.1, 8.9 Hz, 2H), 7.56 (s, 1H), 7.27-7.52 (m, 3H), 7.21 (t, J=7.9 Hz, 2H), 6.96 (t, J=6.6 Hz, 1H), 6.75 (s, 1H), 6.63 (d, J=4.8 Hz, 1H), 4.79-4.97 (m, 1H), 4.07 (q, J=6.7 Hz, 2H), 3.12-3.24 (m, 2H), 3.05 (d, J=11.1 Hz, 2H), 2.98 (s, 3H), 2.61 (t, 2H), 2.14 (s, 3H), 1.62-1.87 (m, 4H), 1.17-1.59 (m, 12H).
