Reaction Steps
To 100 parts of 2-(2,4-dichlorophenyl)-2-methyl-4-(methoxymethyl)-1,3-dioxolane in 480 parts of tetrachloromethane are added at 45° C. a few drops of bromine till the reaction starts. Subsequently 19.6 parts of bromine are added dropwise and the whole is stirred for 2 hours at 20° C. The pale yellow solution is washed with a sodium hydrogen carbonate solution, dried and evaporated. A high vacuum distillation yields 65 parts of pure 2-(2,4-dichlorophenyl)-2-(bromomethyl)-4-(methoxymethyl)-1,3-dioxolane; bp. 129°-132° C. at 0.01 mm. pressure.
