    摘要: The present invention provides a process for synthesizing [6,7-bis(2-methoxyethoxy)quinazolin-4-yl]-(3-ethynylphenyl)amine hydrochloride (Erlitinib Hydrochloride) having the formula (I) comprising reacting 3,4-dihydroxy benzaldehyde with bromo derivative of ethyl methyl ether to obtain 3,4-bis(2-methoxyethoxy)benzaldehyde having formula (III). This is converted to give 3,4- bis (2-methoxyethoxy)-benzonitrile which on furthur nitration we obtain 4,5- bis (2-methoxyethoxy)-2-nitrobenzonitrile which on nitro reduction we get 2-amino-4,5-bis(2-methoxyethoxy)benzonitrile. Formylation of this compound yields N'-[2-cyano-4,5-bis(2methoxyethoxy)phenyl]-N,N-dimethylformamidine. Coupling of this formamidine with 3-ethynyl aniline gives erlotinib free base. On furthur treatment of this free base with methanolic/ethanolic hydrochloric acid gives us erlotinib hydrochloride.
