Procedure
5 g of 4'-methoxymethyl-2-(4,4-dimethyl-2-oxazolinyl)biphenyl hydrochloride, prepared in B/, are dissolved in 75 ml of chloroform stabilised with amylene, and 3.2 ml of boron tribromide are added while cooling to 0° C. The mixture is stirred for one hour at 0° C. and washed with cold water. The organic phase is separated after settling has taken place, then dried over magnesium sulphate and evaporated under vacuum to give 5.2 g of 4'-bromomethyl-2-(4,4-dimethyl-2-oxazolinyl)biphenyl hydrochloride in the form of crystals of melting point 126°-127° C.
