Reaction Steps

To a solution of 3,5-dibromo-imidazo[1,2-a]pyrazine (D) (200 mg, 0.72 mmol) in methanol (3.6 ml) was added (2-morpholin-4-yl-ethyl)-amine (2.5 eq.) and diisopropylethylamine (DIPEA) (0.383 ml, 4.5 mmol). The mixture was heated at 70° C. overnight. The mixture was then cooled to rt, diluted with DCM and water. The organic layer was washed with brine, dried and concentrated. The residue was purified on a silica gel column to give 34 mg (yield 14%) of the title compound.
