Reaction Steps

A mixture of dl-2-(3-methoxyphenyl)-1-phenylethylamine hydrochloride (11.3 g), 48% hydrobromic acid (100 ml) and glacial acetic acid (30 ml) is refluxed for 4 hours. After the reaction, the solvent is distilled off. To the residue is added water and the mixture is made alkaline with ammonia and extracted with chloroform. The chloroform layer is dried over anhydrous potassium carbonate and the solvent is distilled off. To the residue is added ether. The precipitated crystals are separated by filtration and recrystallized from ethanol-ethyl acetate to give the desired compound (7.3 g), melting point: 179°-181° C.
