A solution of [1-methyl-3-(2,6,6-trimethyl-2-cyclohexenyl)-2(trans)-propenyl]dimethylamine (5.0 g) and 1-propylbromide (6.0 g) in absolute methanol (10 cc) was refluxed for 3 hours, and the solvent of the reaction mixture was distilled off under reduced pressure. To the residue were added benzene and ether, and precipitated crystals were gathered by filtration to give colorless crystals (0.8 g) of [1-methyl-3-(2,6,6-trimethyl-2-cyclohexenyl)-2(trans)-propenyl]dimethylpropylammonium bromide.
