In the same way as described for Compound 178, step 4, using (5-bromo-imidazo[1,2-a]pyrazin-8-yl)-[4-(1-methyl-piperidin-4-ylmethoxy)-phenyl]-amine (20 mg, 0.048 mmol), 2-fluoro-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzamide (25.5 mg, 0.10 mmol), Pd(PPh3)4 (13.9 mg, 0.001 mmol) and 1M Na2CO3 (0.8 mL) in dioxane (2 mL). Purification by silica gel column chromatography eluting with a mixture 95:5 followed by 90:10 DCM:MeOH affords a solid that was triturated with ethyl acetate to give the title compound (19.4 mg, 85%). LCMS: Rt 1.96 min (94%), m/z (APCI) 475 (M+H)+; 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 1.48-1.61 (2H, m), 1.98-2.02 (3H, m), 2.51-2.58 (4H, m), 2.70 (3H, br s), 3.91 (2H, d), 6.98 (2H, d), 7.55 (1H, s), 7.65-7.87 (6H, m), 7.98 (2H, d), 8.06 (1H, s), 9.68 (1H, s).
