反応手順
Following the general procedure for amine displacement using 5,8-dibromoimidazo[1,2-a]pyrazine (0.20 g, 0.72 mmol), 3-chloro-4-(4-methyl-piperazin-1-yl)-phenylamine (0.263 g, 1.08 mmol) and DIPEA (0.19 mL, 1.08 mmol) in iPrOH (5 mL). Purification of the crude compound by silica gel column chromatography, eluting with 95:5 DCM:NH3 (7M in MeOH), affords the title compound (60 mg, 20%).
