The invention discloses a preparation method of a 4-aromatic amino pyrrolo-[2, 1-f][1, 2, 4] triazine derivative. The method comprises the following steps: using 3-alkyl-2-cyano pyrrole-4-formic ether as a raw material, successively performing an N-amination reaction, a condensation reaction with N, N-dimethyl formamide dimethyl acetal, and a Dimroth rearrangement reaction, and synthetizing a target compound. Compared with a method of firstly synthetizing pyrrolo-triazone and then performing chloro-substituted and C-4 substituent modification reported in literature, synthetizing pyrrolo- triazine rings and modifying C-4 substituent are realized in a step, reaction steps are simple, reaction conditions are mild, at the same time, halogenating reagents such as phosphorous oxychloride, which are harmful to human bodies and environment, are prevented from being used, and the total recovery of the target compound can reach 21.0%-36.9%.
