N-Methylation of aniline with methanol at elevated temperatures over acid catalysts gives N-methylaniline and N,N-dimethylaniline: C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2H 2 O. N-Methylaniline and N,N-dimethylaniline are colorless liquids with boiling points of 193–195 °C and 192 °C, respectively. These derivatives are of ...
