Reaction Steps
A solution of but-3-ynyl 4-methylbenzenesulfonate (1.14 g), 2-(piperazin-1-yl)pyrimidine (1.06 g) and diisoproylethylamine (1.24 mL) in 1,2-dichloroethane (6 mL) was heated to reflux overnight. The mixture was concentrated, diluted with sat. aq. NaHCO3 (5 mL) and extracted with DCM (2×50 mL). Drying (Na2SO4) and silica gel flash chromatography (EtOAc/hexane 1:1→1:0) afforded 2-(4-(but-3-ynyl)piperazin-1-yl)pyrimidine (0.60 g).
