반응 단계

In the same way as described for compound 127, step 4 using (5-bromo-imidazo[1,2-a]pyrazin-8-yl)-(5-morpholin-4-yl-pyridin-2-yl)-amine (100 mg, 0.266 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (77.6 mg, 0.4 mmol), Pd(PPh3)4 (77 mg, 0.066 mmol) and 1.5M Na2CO3 (1.42 mL, 2.13 mmol) in dioxane (4 mL). The crude compound is purified by silica gel column chromatography eluting with 96:4 DCM:NH3 (7M in MeOH) to afford the title compound which is triturated with diethyl ether (12.9 mg, 8%) and converted into the mesylate salt (6.1 mg, 38%) LCMS: Rt 1.95 min (96%), m/z (APCI) 363 (M+H)+, 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 2.34 (3H, s, MsOH), 3.20 (4H, m), 3.83 (4H, m), 7.38 (1H, br s), 7.64 (1H, br s), 7.71 (1H, s), 7.86 (1H, d), 7.98 (1H, d), 8.04 (2H, m), 8.35 (2H, br s), 8.43 (1H, s).
