Water → 1-(4-Trifluoromethanesulfonylphenyl)piperazine

Participants

Reaction Steps

A mixture of 1 mmol 1-Bromo-4-trifluoromethanesulfonyl-benzene [Nodiff et al., J. Org. Chem. 25, 60 (1960)], 3 mmol of piperazine and 2 mmol of potassium carbonate in 5 ml of acetonitrile was refluxed for 2 hours. The resulting mixture was poured into water, extracted with ethyl acetate, dried, concentrated and purified by column chromatography (SiO2; Et2O/cyclohexane) to yield the title compound as a colorless solid. MS (m/e): 295.2 (MH+, 100%)
