Participants

Reaction Steps

100.32 g (0.41 mol) of 2-bromo-1-(4-fluorophenyl)-2-methylpropan-1-one, prepared by brominating 1-(4-fluorophenyl)-2-methylpropan-1-one (as is described in EP-A-3002), are dissolved in 80 ml of dry methanol and 24.3 g (0.45 mol) of sodium methoxide in a solvent mixture of 60 ml dry methanol and 120 ml of chlorobenzene are added dropwise at 20° C. The methanol is then distilled off and the chlorobenzene solution is concentrated. The liquid crude product (90.8 g) is further purified by distillation at 60° C. and 0.2 mm Hg.
