반응 단계
In the same way as described for Compound 90, step 1, using 5,8-dibromoimidazo[1,2-a]pyrazine (80.5 mg, 0.291 mmol), 4-(4-pyridin-2-yl-[1,2,3]triazol-1-yl)-phenylamine (68.3 g, 0.288 mmol), NaOtBu (38.2 mg, 0.403 mmol), Pd2(dba)3 (10.5 mg, 0.0115 mmol), Xantphos (13.3 mg, 0.023mmol) and toluene (4 mL). The crude material is purified by silica gel column chromatography eluting with 98:2 DCM:MeOH followed by 97:3 DCM:MeOH affording the title compound (52.8 mg, 42%).
