摘要
2-硝基-4-甲氧基-5-[3-(吗啉-4-基)丙氧基]苄腈经钯炭催化转移氢化得到2-氨基-4-甲氧基-5-[3-(吗啉-4-基)丙氧基]苯甲酰胺和2-氨基-4-甲氧基-5-[3-(吗啉-4-基)丙氧基]苄腈的混合物,随后在DMF和五氯化磷作用下转化为N′-[2-氰基-5-甲氧基-4-[3-(吗啉-4-基)丙氧基]苯基]-N,N-二甲基甲脒,最后与3-氯-4-氟苯胺发生Dimroth重排反应得到吉非替尼,总收率约66%。
4-Methoxy-5-(3-morpholinopropoxy)-2-nitrobenzonitrile was converted into the mixture of 2-amino- 4-methoxy-5- (3-morpholinopropoxy) benzamide and 2-amino-4-methoxy-5- (3-morpholinopropoxy) benzonitrile via the transfer hydrogenation catalyzed by Pd/C, and then the mixture was transformed to N'-E2-cyano-5-methoxy-4-(3- morpholin-4-ylpropoxy) phenyl^-N,N-dimethylformamidine (5) in the presence of DMF and phosphoric chloride. Gefitinib was finally obtained through the Dimroth rearrangement of 5 with 3-chloro-4-fluoroaniline. The overall yield was about 66 %.
