Previously unknown 2-aryl-, 2-hetaryl-, and 2-cyclopropyl-5-nitropyridines and 2,3-polymethylene-5-nitropyridines were synthesized by reactions of 1-methyl-3,5-dinitropyridin-2(1H)-one with various cyclic and acyclic ketones in the presence of ammonia.

The reaction of cyclic and non-cyclic enamines with 5-nitropyrimidine has been studied. Many enamines react in an inverse electron-demand Diels-Alderreaction, leading to the formation of 3-nitropyridines. N,S-ketene acetals were also found to react with 5-nitropyrimidine. The mechanism of the reaction will be discussed.
