Dirèk nitril piridin mande sèten kondisyon difisil, epi li jeneralman gen pwodiksyon ti kras. Reyaksyon an nan pentoksid dinitrogen ak piridin nan prezans sodyòm ka rezilta nan fòmasyon nan 3-nitropiridin. Dérivés yo nan piridin ka jwenn nan nitrisyon nan tetrafluoroborate nitronium (NO2BF4) pa davwa atom nitwojèn esterikman ak elektwonikman. Sentèz de de konpoze de pyridine 6-dibromo ka rezilta nan fòmasyon nan 3-nitropiridin apre yo retire nan atòm bromye.

Direct pyridine nitration demands certain harsh conditions, and it generally has little yields. The reaction of dinitrogen pentoxide with pyridine in the presence of sodium can result in the formation of 3-nitropyridine. The derivatives of pyridine can be obtained through nitration of nitronium tetrafluoroborate (NO2BF4) by picking nitrogen atom sterically and electronically. Synthesis of two compounds of 6-dibromo pyridine can result in the formation of 3-nitropyridine after removal of bromine atoms.
