Reaction Steps

A solution of pent-4-ynyl methanesulfonate (1.05 g), 2-(piperazin-1-yl)pyrimidine (1.02 g) and diisoproylethylamine (1.2 mL) in THF (5 mL) was heated to reflux overnight. The mixture was concentrated, diluted with aq. NaOH 2M (10 mL) and extracted with DCM (2×50 mL). Drying (Na2SO4) and silica gel flash chromatography (EtOAc/hexane 2:1→2:0) afforded 2-(4-(pent-4-ynyl)piperazin-1-yl)pyrimidine (0.95 g).
