Reaction Steps

1-(3-Bromo-5-methoxyphenyl)ethanone (O2.032, 1.45 g) was dissolved in methanol/THF (40 ml/40 ml) and admixed while stirring with phenyltrimethylammonium tribromide (2.38 g). After stirring at RT for 24 h, water and EA were added. The EA phase was removed, dried and concentrated. The residue was dissolved in acetonitrile (50 ml), and 2 N sulfuric acid (15 ml) was added to the solution. After standing at RT for 1 h, the mixture was admixed with water and extracted twice with EA. The EA phase was washed with saturated sodium hydrogencarbonate solution, dried and concentrated. The residue was purified using silica gel (40 g cartridge, n-heptane/EA gradient of 0-50% within 30 min). 1.39 g of the title compound were obtained.
