Hydrogen Peroxide → 4-Methoxy-3-phenylphenethylamine

Participants

Reaction Steps

A mixture of tetrakis triphenylphosphine palladium (7 g), 3-bromo-4-methoxyphenethylamine hydrobromide (62.2 g) and toluene (400 ml) was stirred under nitrogen with 2M aqueous sodium carbonate solution (200 ml) and then a solution of phenyl boric acid (26.8 g) in ethanol (100 ml) was added. The mixture was heated under reflux for 48 hours then cooled and treated with 30% aqueous hydrogen peroxide solution (10 ml). The mixture was stirred at ambient temperature for 1 hour. The aqueous layer was separated and extracted with ether. The ether extracts were combined with the original organic phase. Distillation yielded 4-methoxy-3-phenylphenethylamine which was used without further purification.
