The Skraup synthesis with m-ethylaniline has been shown to give a mixture of 7-ethylquinoline (75%) and 5-ethylquinoline (25%). Pure 7-ethylquinoline has been isolated as a solid. Nitration of 7-methyl- and 7-ethylquinolines gives only the 8-nitro derivatives; the minor products from the nitration of impure samples of 7-alkylquinolines arise from the 5-alkyl- contaminants. 5-Methylquinoline is nitrated
所述Skraup合成与米-ethylaniline已经显示出,得到7-乙基喹啉(75%)和5-乙基喹啉(25%)的混合物。已分离出纯净的7-乙基喹啉固体。7-甲基-和7-乙基喹啉的硝化仅产生8-硝基衍生物。不纯净的7-烷基喹啉样品硝化的次要产物来自5-烷基污染物。5-甲基喹啉在6和8位被硝化。
