A mixture of 11.8 parts of 3-(2,6-dimethylphenoxy)-1,2-propanediol, 13.6 parts of 2-bromo-1-(2,4-dichlorophenyl)-1-ethanone, 3 parts of 4-methylbenzenesulfonic acid, 80 parts of butanol and 180 parts of methylbenzene is stirred and refluxed for 3 days. The reaction mixture is evaporated and the residue is dissolved in 2,2'-oxybispropane. The solution is stirred for 30 minutes with silica gel. The latter is filtered off and the filtrate is evaporated, yielding A+B 2-(bromomethyl)-2-(2,4-dichlorophenyl)-4-(2,6-dimethylphenoxymethyl)-1,3-dioxolane as a residue.
