Potassium Carbonate → 1-Benzyl-4-glycidylpiperazine

Participants

Reaction Steps

To a solution of 2-bromomethyl-oxirane (2.3 mL, 27.5 mmol) in 40 mL of ACN are added K2CO3 (3.8 g, 27.5 mmol) and a solution of 1-benzyl-piperazine (5.81 g, 25 mmol) in 60 mL of ACN. After 24 hr at rt the reaction is judged to be completed by tlc monitoring (SiO2, DCM:MeOH 20:1). The reaction mixture is filtered off and the filtrate is concentrated in vacuo. Flash chromatography on a 7×15 cm2 column of SiO2 using DCM:MeOH (20:1) as eluting solvent and removal of the solvent gives the title compound (4.87 g, 84%) as a colorless oil.
