Phenethyl bromide → N,N-Dimethylphenylethylamine

Participants

Reaction Steps

2-Phenylethyl bromide [0.01 mol.] and dimethylamine hydrochloride [0.02 mol.] are stirred at room temperature [24 hrs] and then refluxed [1 hr.] with potassium carbonate [0.06 in methanol. The insoluble materials are filtered and the solution evaporated and distilled to form N,N-dimethyl-2-phenylethylamine. The hydrochloride salt [m.p. 163-4° C.] is formed and recrystallized from ethanol. The structure was confirmed by its proton nmr spectrum, by its chemical ionization mass spectrum, and its correct elemental analyses.
