Trimethylhexamethylenediamine is synthesized from isophorone.^[2] Isophorone is reduced by hydrogenation to the trimethylcyclohexanol, which is then oxidized with nitric acid (in the same fashion as adipic acid is synthesized from cyclohexane). The diacid is converted to the diamine via the dinitrile.^[3]
