Dimethylaniline is used in dye manufacturing as an intermediate. Refer to JACS 69 (1947) pg. 1907-1908
3,5-dimethylcyclohexenone azine can be converted to 3,5-dimethylaniline by heating in an inert solvent with a pd/c catalyst. Triethylbenzene has been found to be the best solvent to aromatizise the azine. 50% yield has been documented with triethylbenzene Diphenyl ether gavea maximum yield of 44%. Best probably to try and aquire it. There are also patents out there about preparation of tertiary amines

Anyone else have any information on Dimethylaniline. Preferably OTC. As the above post from carboxyl
is all good but the chems are just as hard to get as Dimethylaniline itself.any help would be much appreciated.

Benzene -> Nitrobenzene -> Aniline -> N,N-Dimethylaniline

Step 1: Sulfuric and Nitric acid, described at the hive, UTFSE
Step 2: Reduction with iron or tin, described at the hive, UTFSE
Step 3: Eschweiler-Clarke reaction (formaldehyde/formic acid), described at the hive, UTFSE
