, (2020/05/02)
The invention relates to a synthesis method of imatinib and imatinib mesylate. The method comprises the following steps: condensing 3-acetylpyridine and N,N-dimethylformamide dimethyl acetal which aretaken as initial raw materials to obtain 3-dimethylamino-1-(3-pyridyl)-2-propen-1-one, then reacting with 2-methyl-5-nitrophenylguanidine nitrate to form a pyrimidine ring, performing nitro reductionto obtain N-(5-amino-2-methylphenyl)-4-(3-pyridyl)-2-pyrimidinamine, amidating the N-(5-amino-2-methylphenyl)-4-(3-pyridyl)-2-pyrimidinamine and 4-(chloromethyl)benzoyl chloride, performing affinitysubstitution with 1-methylpiperazine to obtain imatinib, and salifying the imatinib and methanesulfonic acid. The products obtained by the method have the advantages of few impurities, simplicity in post-treatment, high total yield, greenness, environmental protection and safety, and is suitable for a production process for large-scale industrial production of imatinib mesylate.
