2,4-Dichlorobenzyl chloride → [1-Methyl-3-(2,6,6-trimethyl-2-cyclohexenyl)-2(trans)-propenyl]dimethyl(2,4-dichlorobenzyl)ammonium chloride

Participants

Reaction Steps

A mixture of [1-methyl-3-(2,6,6-trimethyl-2-cyclohexenyl)-2(trans)-propenyl]dimethylamine (2.0 g), α,2,4-trichlorotoluene (3.0 g) and methanol (10 cc) was refluxed for 5 hours, and the solvent of the reaction mixture was distilled off under reduced pressure. The residue was dissolved in a small amount of benzene and thereto was added a large amount of ether. The precipitated oil was gathered by decantation and dissolved in a small amount of benzene and thereto was further added a large amount of ether. The solvent was distilled off to give colorless oil (4.5 g) of [1-methyl-3-(2,6,6-trimethyl-2-cyclohexenyl)-2(trans)-propenyl]dimethyl(2,4-dichlorobenzyl)ammonium chloride.
