Document Type and Number:
WIPO Patent Application WO/2020/259078
Kind Code:
A1
Abstract:
Provided is a method for preparing an adamantyl-containing triphenylamine derivative, the method comprising first reacting an aryl halogenated adamantane or an aryl adamantane ester with a primary aromatic amine without separation or purification after a reaction, and directly adding a halogenated aromatic hydrocarbon for reaction. The method not only has fewer reaction steps and can ensure one final separation and purification, but can also reduce the content of impurities, further increases the yield of the product, and prepares the target product in a higher yield. In addition, the steps of the present invention are simple, the raw materials used are basic chemical raw materials, the yield is high, and the finally prepared product has a high purity. The method is superior to the prior art in terms of the cost of raw materials, the actual operability and the working hours required for operation, and is very suitable for industrial production.
