Reaction Steps

5,8-Dibromo-3-methylimidazo[1,2-a]pyrazine (270 mg, 0.93 mmol) and 4-morpholinoaniline (200 mg, 1.1 mmol) are combined in nBuOH (10 mL) and DIPEA (240 μL, 1.4 mmol) is added. The mixture is heated at reflux for 10 h, cooled and the solvent removed under reduced pressure. The residue is purified by silica chromatography, eluting with 12%-100% EtOAc in cyclohexane, to afford the title compound as a red-brown solid (190 mg).
