3 -methyl - 4 - (4' - diethylamino - 1' - methylbutyl- amino)-quinolines have been studied and the in- fluence of halo-substitution has been discussed critically. Spectral changes due to the influence of the methyl or propyl groups in the 3- position, as well as the influence of the methyl group in position 2 has been pointed out. The 4-diethylamino- 1 -methylbutylamino side chain has been replaced by eight other side chains and the resulting spectra have been ...
