Reaction Steps
In the same way as described for Compound 90, step 3, using 4-(5-bromoimidazo[1,2-a]pyrazin-8-ylamino)benzoic acid (365 mg, 1.57 mmol), 3-aminomethylpyridine (0.16 mL, 1.57 mmol), N,N-diisopropylethylamine (0.42 mL, 2.35 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) (715 mg, 1.9 mmol) and DMF (6 mL). The crude residue is purified using column chromatography, eluting with EtOAc followed by EtOAc:MeOH (95:5) then EtOAc:NH3 (7M in MeOH). The title amide is isolated as a solid.
