Yield:87394-48-7 95%
Reaction Conditions:
in acetonitrile;Heating / reflux;
Steps:
17.1
Example 17.1: 1 -(3-Nitro-pyridin-2-yl)-piperazine. A mixture of 2-chloro-3-nitro-pyridine (2,0 g, 0.013 mol), piperazine (5.43 g, 0.063 mol) and acetonitrile (50 mL) was heated at reflux overnight. The reaction mixture was cooled to room temperature, diluted with ethyl acetate, washed with water and washed with brine. The organic layer was separated, dried over sodium sulfate, filtered and concentrated to give l-(3-nitro-pyridin-2-yl)-piperazine (2.5 g, 95 %). The product was used without further purification.
