Reaction Steps
2-Chloro-5-nitrobenzonitrile (13.3 g) and cis-2,6-dimethylpiperazine (25 g) were added to acetonitrile (25 ml) and the mixture was stirred at room temperature for 1 h. The reaction mixture was added to water and extracted with chloroform. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was recrystallized from diisopropyl ether to give cis-2-(3,5-dimethylpiperazin-1-yl)-5-nitrobenzonitrile (14.3 g), melting point: 109–110° C.
