Synthesis of 6-methoxy-N 2,N 2,N 4,N 4,N 5,N 5-hexamethylquinoline-2,4,5-triamine – a new representative of quinoline proton sponges
Tóm tắt
We report the synthesis of 4-chloro-2-methyl-5-nitro- and 2,4-dichloro-5-nitroquinolines, containing methoxy groups at positions 6 and 8. The reaction of these compounds with dimethylamine solution in alcohol was shown to produce not only aminodehalogenation products, but also resulted in nucleophilic substitution of the methoxy groups. The reduction of 6-methoxy-N
