Reaction Steps

3 g (14.7 mmol) of 2-chloro-3,5-dinitropyridine, 10 ml of THF and 30 mmol of 4-piperidine carboxamide were placed in a round-bottomed flask. The mixture was maintained at 60° C. for 15 hours with stirring and was then poured into an ice-water mixture with stirring. The precipitate formed was filtered off by suction and dried under vacuum to constant weight. 0.522 g of yellow powder was obtained.
