Abstract

The invention relates to the field of organic synthesis, in particular to a novel method for synthesizing osimertinib through molecular sieve catalysis. N-1-[2-(dimethylamino) ethyl]-5-methoxy-N1-methyl-N4-[4-(1-methyl-1H-indole-3-yl-2-pyrimidinyl]-1,2,4-triaminobenzene and acrylic acid as raw materials, acrylic acid is added into an alcohol solvent, reaction is carried out through molecular sievecatalysis and microwave heating, and after the reaction is completed, post-treatment is carried out to obtain the osimertinib. According to the method, the reaction conditions are mild, industrial production is facilitated, the raw materials are environmentally friendly in use, used highly toxic raw materials are decreased, the yield is high, and the reaction efficiency is high.

Description

technical field [0001] The invention relates to the field of organic synthesis, in particular to a method for synthesizing osimertinib by catalyzing molecular sieves. Background technique [0002] AZD9291 is a third-generation irreversible epidermal growth factor receptor tyrosine kinase inhibitor for the activation of resistant mutant EGFR. In April 2014, the U.S. Food and Drug Administration (FDA) awarded AZD9291 the title of "Breakthrough Therapy Drug". Targeted drugs for side effects such as rashes. [0003] AZD9291 chemical name: N-{2-[[2-(dimethylamino)ethyl]methylamino]-4-methoxy-5-[[4-(1-methyl-1H-indole -3-base)-2-pyrimidinyl]amino]phenyl}-2-acrylamide, its structural formula is: [0004] [0005] Aniline Osimertinib intermediate N1-[2-(dimethylamino)ethyl]-5-methoxy-N1-methyl-N4-[4-(1-methyl-1H-indole-3 -yl)-2-pyrimidinyl]-1,2,4-benzenetriamine and 3-chloropropionyl chloride to synthesize osimertinib N-{2-[[2-(dimethylamino)ethyl]methyl Amino]-4-methoxy-5-[...
