Reaktionsschritte

In the same way as described for Compound 90, step 1, using 5,8-dibromoimidazo[1,2-a]pyrazine (116.9 mg, 0.422 mmol), 4-(4-dimethylaminomethyl-[1,2,3]triazol-1-yl)-phenylamine (91.7 g, 0.422 mmol), NaOtBu (56.8 mg, 0.591 mmol), Pd2(dba)3 (15.5 mg, 0.0169 mmol), Xantphos (19.5 mg, 0.0337 mmol) and toluene (5 mL). The crude product is purified by Isolute FlashSilicaII cartridge chromatography eluting with 99:1 DCM/NH3 (7M in MeOH), followed by 97:3 DCM:NH3 (7M in MeOH). The title compound (63 mg, 36%) is isolated after a second column chromatography purification eluting with 97:3 DCM:NH3 (7M in MeOH).
