Participants

Reaction Steps

60 g (0.30 mols) of 3-bromoacetophenone are dissolved in 800 ml of ethanol and mixed with 250 ml of dimethylamine. The pH of the solution is adjusted to 6.5 with acetic acid. The reaction mixture is then cooled to 0° and mixed with 19 g of sodium cyanoborohydride. After stirring for 2 days at room temperature, the reaction mixture is concentrated. The residue is mixed with 800 ml of water and acidified. The solution is then extracted twice with 400 ml of ether, the aqueous phase is rendered basic and extraction follows 3× with 400 ml of ether. The combined organic extracts are dried and concentrated. After distillation of the residue, the 3-bromo-N,N,α-trimethylbenzenemethanamine is obtained; b.p.: 98°-100°/10 mmHg.
