Participants

Reaction Steps

1.0 g (5.21 mmol) of 3,4-dichloronitrobenzene (Fluke, Buchs, Switzerland), 624 mg (5.47 mmol) cis-2,6-dimethylpiperazine (Aldrich, Buchs, Switzerland) and 580 mg (5.73 mmol) triethylamine in 20 ml of EtOH are heated in a microwave oven at 170° C. for 6 h and 180° C. for 2 h. The reaction mixture is evaporated to dryness and then taken in EtOAc. The organic layers is extracted with 1 M aqueous HCl (5×) and the combined aqueous layers are basified with NaHCO3 and extracted with CH2Cl2 (3×), washed with brine, dried over MgSO4, filtered and evaporated to dryness to give the title compound as a yellow solid. ES-MS: 270 (M+H)+; analytical HPLC: tret=2.72 minutes (Grad 1).
