Abstract
A process for the manufacture of tertiary amines of the general formula: ** (See formula) ** where X means radicals 25-endomethylene-cyclohexen- (3) -ylocyclohexylcyclohexylene-4-oxy-3-methoxyphenyl-34-dimethoxyphenylonaphthylanthranilofurilotienyl or a radical 5- 6-dihydropyranyl and R1 and R2 signify an alcohol-oxycoalhylcycloalcohiloaryl or aralcohil group, and R1 and R2 may be the same or different or also together with N form a heterocyclic ring that eventually contains another heteroatomophor example pyrrolidinicopiperidinicoo morfolinicoe ring Y represents an alcoholiccycloalcohiloaryl or aralcohil group and may be substituted aryl and aralkohilic groups characterized by alpha-tertiary (**) formula (**). they are reacted with organomagnesic halides of the formula Y-Mg-Hal where XR1 R2 and Y have the significance indicated above in the presence of solvent s and eventually the reaction products obtained are transformed in a manner known per se into quaternary ammonium compounds.
