Participants

Reaction Steps

710 mg of 2-(4-ethylphenoxy)methoxybenzene 70 are dissolved in 5 ml absolute dichloromethane. 0.6 ml of boron tribromide (1 M dichloromethane) is added dropwise, and the solution stirs for 6 h. Further BBr3 is added and the mixture is stirred until the reaction is almost complete according to LCMS. The solution is brought into ice-water, the organic phase is separated off, and the aqueous phase is extracted three times with dichloromethane. The combined organic phase is dried, evaporated to dryness and purified by chromatography. 450 mg of the desired product are obtained. C14H14O2 (214.27) MS (ESI): 215.10 (M+H+).
