Reaction Steps
A mixture of 6.1 mmol 2-chloroquinoline, 6.7 mmol piperazine-1-carboxylic acid tert-butyl ester and 12.2 mmol potassium carbonate in 15 ml acetonitrile was refluxed overnight. The reaction mixture is concentrated, water is added and the compound extracted with ethyl acetate. Chromatography (SiO2; cyclohexane/ethyl acetate 9/1) gave the title compound as a colorless solid.
