In the same way as described for Compound 178, step 4, using (5-bromo-imidazo[1,2-a]pyrazin-8-yl)-[4-(4-dimethylaminomethyl-[1,2,3]triazol-1-yl)-phenyl]-amine (63 mg, 0.152 mmol), 4-(aminocarbonyl)phenylboronic acid (50.3 mg, 0.305 mmol) 1.5 M Na2CO3 (0.813 mL, 1.22 mmol) and Pd(PPh3)4 (44.0 mg, 0.0381 mmol) in (2:1) DMF-dioxane (1.8 m1L). Purification of the crude material by Isolute FlashSilicaII Cartridge chromatography eluting with 95:5 DCM:NH3 (7M in MeOH) followed by reverse phase preparative HPLC, affords the title compound as a white solid (4.7 mg, 7%). LCMS: Rt 1.92 min (96%) m/z (APCI) 455 (M+H)+; 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 2.24 (6H, s), 3.61 (2H, s), 7.51 (1H, br s), 7.64 (1H, s), 7.80 (1H, s), 7.85-7.91 (4H, m), 8.08-8.12 (3H), m), 8.16 (1H, br s), 8.36 (2H, d), 8.66 (1H, s), 10.09 (1H, s).
