Reaction Steps

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 x), 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.
