Reaction Steps

A mixture of 14.4 parts of 1-[2-(4-methylphenyl)ethyl]-ethanediol, 15.6 parts of 2-(bromomethyl)-2-(2,4-dichlorophenyl)-1,3-dioxolane, 5 parts of 4-methylbenzenesulfonic acid, 225 parts of methylbenzene and 40 parts of butanol is stirred and refluxed for 3 days with water-separator. 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 2-(bromomethyl)-2-(2,4-dichlorophenyl)-4-[2-(4-methylphenyl)ethyl]-1,3-dioxolane as a residue.
