2.2 g (0.03 mol) of pyrrolidine were added over 10 minutes to a solution containing 3 g (0.015 mol) of 2-chloro-3,5-dinitropyridine in 30 ml of dioxane, at 40° C. The reaction medium was maintained at 60° C. until the reagents disappeared. The reaction medium was then poured into a water/ice mixture with vigorous stirring and the precipitate was filtered off by suction, washed with water and then dried to constant weight to give 3.2 g of 3,5-dinitro-2-pyrrolidin-1-ylpyridine.
