| Product | 1-(Pent-4-yn-1-yl)piperazine | HCID 86608221 | 24% |
Reaction Steps
A solution of pent-4-ynyl methanesulfonate (19.55 g) and piperazine (41.5 g) in EtOH (80 mL) was heated to reflux for 1 h, and evaporated. The residue was taken in NaOH 2M (70 mL) and extracted with Et2O (70 mL). Evaporation gave 1-(pent-4-ynyl)piperazine (4.4 g).
