-
Paragraph 0027-0029, (2019/05/06)
The invention relates to a preparation method for an EGFR molecule targeting antitumor drug, and provides a preparation method for (E)-N-[4-(3-acetylene phenyl)amino-3-cyan-7-ethoxy-6-quinolyl]-4-(dimethyl amino)-2-butylene amide. The preparation method comprises the following steps: N-(4-chloro-3-cyan-7-ethoxy quinoline-6-yl) acetamide (a compound II) and 3-aminophenylacetylene (a compound III) are subjected to a substitution reaction, and a compound IV is obtained; under an acidic or alkaline condition, the compound IV is subjected to a hydrolysis reaction, and 3-cyan-6-amino-7-ethoxy-4-(3-acetenyl anilino) quinoline (a compound V) is obtained; after trans-4-dimethylaminocrotonic acid hydrochloride (a compound VI) and an acylation reaction reagent is subjected to an acylation reaction, the product and 3-cyan-6-amino-7-ethoxy-4-(3-acetenyl anilino) quinoline (the compound V) are subjected to condensation reaction, and the finished product is obtained. The method is advantageous in that raw materials are easily available, the technology is concise, the production cost is low, and the method is economical and environmentally friendly and is suitable for industrial production.
