Procedure

Homopiperazine (15.58 g) is dissolved in 100 ml of acetonitrile. Potassium carbonate (8.7 g) is added and then the 2-chloro-3-nitropyridine (5.0 g) dissolved in 25 ml of acetonitrile is added dropwise. The reaction is stirred at 20°-25° 4 hr, then diluted with methylene chloride, washed with water (2×), saline, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound, NMR (300 MHz, CDCl3) 8.30, 8.08, 6.66, 3.60, 3.41, 3.10, 2.89 and 1.93 δ.
