Paragraph 0010; 0042; 0046; 0047; 0048; 0049, (2017/09/23)
The invention belongs to the field of organic synthesis and particularly relates to a preparation method of SYP-14288. The method includes the steps of: adding a reaction solvent A to 2,6-dichloro-3,5-dinitrotoluene, adding dropwisely ammonia water or feeding ammonia gas to the solution at from 0 DEG C to reflux temperature of the solvent A, continuously performing the reaction for 1-10 h, and removing the solvent after the reaction is finished to obtain an intermediate substituted ammoniated substance; performing a reaction to the substituted ammoniated substance, 3,5-dichloro-4-fluoronitrobenzene, an alkali and a reaction solvent B for 1-20 h at from room temperature to reflux condition of the solvent B; and removing the solvent after the reaction is finished, performing post-treatment to obtain a crude product, and re-crystallizing the crude product to obtain the product, SYP-14288. The product SYP-14288 is high in purity and yield. The method employs easy-to-obtained raw materials, has simple operations and mild reaction conditions, and is suitable for industrial production.
