A mixture of 13.6 parts of 2-bromo-1-(2,4-dichlorophenyl)-1-ethanone, 14.1 parts of 1-[2-(2,4-dichlorophenyl)ethyl]ethanediol, 3 parts of 4-methylbenzenesulfonic acid, 80 parts of butanol and 180 parts of benzene is stirred and refluxed for 24 hours. The reaction mixture is evaporated and the residue is stirred for 2 hours with 160 parts of methanol. The precipitated product is filtered off, yielding 2-(bromomethyl)-2-(2,4-dichlorophenyl)-4-[2-(2,4-dichlorophenyl)ethyl]-1,3-dioxolane.
