The invention discloses a preparing method of halogenated nitrogenous unsaturated cyclic hydrocarbon. The preparing method comprises the steps of 1, dissolving nitrogenous unsaturated cyclic hydrocarbon into hydrochloric acid or hydrobromic acid, adding an oxidizing agent, making a reaction system subjected to a halogenated reaction, conducting sampling detection regularly in the reaction process,and adding a terminator into the reaction system to terminate the reaction when it is detected that the mass of a target product monohalide accounts for 70-95% of the total organic matter in the reaction system, so that feed liquid containing nitrogenous unsaturated cyclic hydrocarbon is obtained; 2, adding an organic solvent into the feed liquid for extraction, obtaining an organic phase after extraction, and cooling the organic phase to make a solid substance separated out of the organic phase, or distilling the organic phase to remove the solvent and obtain a liquid product, wherein the solid substance or the liqu
