Participants

Reaction Steps

A mixture of 6 parts of 2-bromo-2',4'-dichloroacetophenone, 6 parts of 3-(4-chloro-o-tolyloxy)-1,2-propanediol, 3 parts of p-toluenesulfonic acid, 80 parts of n-butanol and 180 parts of benzene is stirred and refluxed for 24 hours with water-separator. The solvent is removed in vacuo and the residue is triturated in methanol. The product is filtered off and crystallized from petroleumether, yielding A+B 2-(bromomethyl)-4-(4-chloro-2-tolyloxymethyl)-2-(2,4-dichlorophenyl)-1,3-dioxolane.
