Condensation of 2-aminoacetophenone and 2-aminobenzophenone with ethyl 4-chloro-3-oxobutanoate in the presence of excess chlorotrimethylsilane was shown to give ethyl 2-chloromethyl-3-quinoline carboxylates in high yields. A similar reaction with 1,3-dichloroacetone and 2-chlorocyclohexanone led to the 3-chloro-2-(chloromethyl)quinolines and 4-chloro-1,2,3,4-tetrahydroacridines, respectively.
在过量氯三甲基硅烷存在下,2-氨基乙酰苯酮与2-氨基苯基酮与乙基4-氯-3-氧代丁酸酯的缩合反应显示出能高产率地生成乙基2-氯-甲基-3-喹啉羧酸酯。与1,3-二氯丙酮和2-氯环己酮进行类似反应则分别得到3-氯-2-(氯甲基)喹啉和4-氯-1,2,3,4-四氢阿克里丁。
