To a solution of 3,5-dibromo-imidazo[1,2-a]pyrazine (D) (200 mg, 0.72 mmol) in THF (3.6 ml) was added butylamine (2.2 ml, 21.6 mmol). The mixture was heated at 70° C. for 3 hr. The mixture was then cooled to rt, and diluted with DCM. The organic layer was washed with water, brine, dried and concentrated. The residue was purified on a silica gel column to afford 99 mg (yield 51%) of (3-bromo-imidazo[1,2-a]pyrazin-8-yl)-butyl-amine.
