반응 단계
Following the general procedure for amine displacement using 5,8-dibromoimidazo[1,2-a]pyrazine (0.50 g, 1.81 mmol), 3-fluoro-4-(4-methyl-piperazin-1-yl)-phenylamine (0.45 g, 2.17 mmol) and DIPEA (0.47 mL, 2.72 mmol) in iPrOH (5 mL). The crude material is purified by silica gel column chromatography eluting with 90:10 DCM:MeOH to give the title compound (35 mg, 5%).
