4-dialkoxyanilines with ethyl (ethoxymethylene)cyanoacetate followed by thermal cyclization gave, regiospecifically, 6,7-dialkoxy-4-oxo-1, 4-dihydroquinoline-3-carbonitriles. Chlorination (POCl(3)) followed by the reaction with substituted anilines furnished the 4-anilino-6, 7-dialkoxyquinoline-3-carbonitrile inhibitors of EGF-R kinase. An alternate synthesis of these compounds starts with a methyl 3, 4-dialkoxybenzoate
描述了表皮生长因子受体(EGF-R)激酶的一系列4-苯胺基-6,7-二烷氧基喹啉-3-甲腈抑制剂的合成和SAR。将3,4-二烷氧基苯胺与(乙氧基亚甲基)氰基乙酸乙酯缩合,然后热环化,区域特异性地得到6,7-二烷氧基-4-氧代-1,4-二氢喹啉-3-甲腈。氯化(POCl(3)),然后与取代的苯胺反应,提供了EGF-R激酶的4-苯胺基-6,7-二烷氧基喹啉-3-甲腈抑制剂。这些化合物的另一种合成方法是从3,4-二烷氧基苯甲酸甲酯开始。硝化然后还原(Fe,NH(4)Cl,MeOH-H(2)O),得到2-氨基-4,5-二烷氧基苯甲酸甲酯。使用DMF-乙缩醛形成formation,然后使用LiCH(2)CN环化,得到6,7-二烷氧基-4-氧代-1,4-二氢喹啉-3-腈 像以前一样进行了改造。还制备了在喹啉环的3-位上含有酸,酯,酰胺,甲醇和醛基的化合物,以及几种1-苯胺基-6,7-二甲氧基异喹啉-4
