, (2019/02/13)
The invention discloses a 1 - [...] synthetic preparation method, comprises the following steps: S1) will anthracene and acetyl chloride is dissolved in the solvent, and the catalysis of a Lewis acid, reaction to obtain the 1 - b [...]; S2) 1 - b [...] through oxidation reaction, to obtain 1 - carboxylic acid anthracene; S3) under the action of the acyl, firstly the 1 - anthracene acid radical chloride acid, to remove the surplus solvent, followed by reaction with cyanide, to produce the target compound 1 - cyanate anthracene. The present invention provides 1 - [...] synthetic preparation method, in order to low-cost transfer catalyst, acetyl chloride as the raw material, after three step synthesis of simple and convenient operation, and then after treatment and purification, can prepare and get the purity 98% or more of 1 - [...], not only the production cost is low, the experimental steps are few, simple operation, and after the simple purification, the purity can reach 98% above, can fully meet the T - 2 toxin of the derivatization detection, greatly reduce the T - 2 toxin detection cost.
