Versuchsvorschrift

In the same way as described for Compound 178, step 4, using (5-bromo-imidazo[1,2-a]pyrazin-8-yl)-[6-(4-isopropyl-piperazin-1-yl)-pyridin-3-yl]-amine (0.05 g, 0.12 mmol), 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-2,3-dihydro-isoindol-1-one (0.056 g, 0.22 mmol), 1.5M Na2CO3 (0.64 mL, 0.96 mmol) and Pd(PPh3)4 (0.042 g, 0.36 mmol) in dioxane (2 mL). Purification using silica gel column chromatography, eluting with DCM followed by 99:1 and 97:3 DCM:NH3 (7M in MeOH), affords the title compound as a yellow solid (28 mg, 50%). Conversion into the mesylate salt, as described for Compound 178, step 4, affords the title compound as a yellow solid (32 mg, 95%). LCMS: Rt 2.70 min (92%); m/z (APCI) 469 (M+H)+; 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 1.34 (6H, d), 2.34 (3H, s, MsOH), 3.10-3.21 (4H, m), 3.57-3.59 (3H, m), 4.43 (2H, d), 4.52 (2H, s), 7.08 (1H, d), 7.52 (1H, s), 7.77-7.94 (4H, m), 8.07 (1H, s), 8.30 (1H, d), 8.75 (1H, s), 8.83 (1H, br s), 9.34 (1H, br s), 9.88 (1H, br s).
