Methanol → N,N,N-Trimethyl(3-methylphenyl)methanaminium bromide

Participants

Reaction Steps

A] 3-Methylbenzyl bromide (24.64 g, 1.33×10−1 mol, Aldrich) is dissolved in 221 g of diethyl ether in a 500 ml round bottomed flask. A 33% (w/w) solution of trimethylamine in methanol (35.80 g, 2.00×10−1 mol, Acros) is added all at once, forming a precipitate almost immediately. The reaction mixture is allowed to stir overnight at room temperature and is then filtered and washed three times with diethyl ether. The resulting powder is dried in a vacuum oven overnight to obtain 3-methylbenzyl trimethylammonium bromide.
