Reaction Steps

To a solution of 1-acetylpiperazine (5.0 g; 39.0 mmol) in THF (50 ml) was added triethylamine (5.6 ml; 39.0 mmol) and 3-nitrobenzylbromide (8.4 g; 39.0 mmol). The mixture was stirred at ambient temperature for 1 hour and the solvent was removed by evaporation. The residue was partitioned between water and ethyl acetate. The organic phase was dried over sodium sulphate and evaporated under reduced pressure to leave 6m2, quantitatively.
