Reaction Steps
A mixture of 13.4 parts of 2-bromo-2',4'-dichloroacetophenone, 8.4 parts of α-(hydroxymethyl)benzyl alcohol, 1.15 parts of p-toluenesulfonic acid, 160 parts of benzene and 140 parts of n-butanol is stirred and refluxed for 48 hours with a water-separator. The solvent is removed in vacuo. The residue is purified by column-chromatography over silica gel, using chloroform as eluent. The pure fractions are collected and the eluent is evaporated, yielding 2-(bromomethyl)-2-(2,4-dichlorophenyl)-4-phenyl-1,3-dioxolane as residue.
