Reaction Steps

In the same way as described for Compound 127, step 4, using 2-fluoro-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)benzamide (82 mg, 0.31 mmol), (5-bromoimidazo[1,2-a]pyrazin-8-yl)-(4-(4-methylpiperazin-1-yl)phenyl)amine (60 mg, 0.155 mmol) and Pd(PPh3)4 (45 mg, 0.038 mmol) in dioxane (2.2 mL) and 1.5M Na2CO3 (0.83 mL). The residue is chromatographed on silica gel, eluting with DCM followed by 96:4 DCM:NH3 (7M in MeOH), and the fractions containing the desired product are combined and evaporated. The residue is triturated with Et2O to afford the title compound as a solid. HPLC (254 nm): Rt 1.94 min (93.5%); m/z (APCI) 446 (M+H)+
