20.2 g bromacetylbromide was dropped to 16.5 g 1-pyrimidin-2-yl-piperazin and 10.2 g triethylamine in 250 mL THF. The reaction mixture was stirred overnight at RT and evaporated. The residue was extracted with DCM and water. The organic layer was evaporated and the residue was crystallized with petrolether and then purified by chromatography on silica gel (DCM/MeOH:95/5) to yield 8.9 g of the desired compound.
