Reaction Steps

To a vial was added 4-fluoronitrobenzene (1.41 g, 1.06 mL, 0.01 mol), DIEA (1.92 mL, 0.011 mmol), isopropylpiperazine (1.41 g, 0.011 mmol), and DMF (10 mL). Mixture was heated at 100° C. for 48 h in a sealed tube. The reaction mixture was cooled to RT and concentrated. The residue was purified via silica gel column chromatography (gradient elution with 0 to 10% MeOH in DCM) to afford 1-isopropyl-4-(4-nitrophenyl)piperazine.
