Reaction Conditions

Temperature80 °C

Reaction Steps

3.76 ml (35.082 mmol) of 4-fluoronitrobenzene are dissolved in 40 mL DMA and combined with 9.25 mL (52.62 mmol) of N-ethyldiisopropylamine and 7.6 ml (38.59 mmol) of 1-(benzyloxycarbonyl)-piperazine. The reaction mixture is stirred for 18 h at 80° C. Then the solvent is eliminated in vacuo and the crude product is purified by chromatography. The carrier material used is silica gel and the eluant used is a mixture consisting of cyclohexane:ethyl acetate (50:50).
