Water → 3-(4-Bromophenyl)propane-1,2-diol

Participants

Reaction Steps

A mixture of 90 parts of 2-(4-bromophenylmethyl)oxirane, 8 parts of ethanedioic acid, 100 parts of water and 300 parts of 1,4-dioxane is stirred and refluxed overnight. The reaction mixture is evaporated. The residue is dissolved in trichloromethane. The solution is washed with 110 parts of a sodium hydroxide solution 10%, dried, filtered and evaporated. The residue is distilled (bp. 165° C. at 0.6 mm. pressure). The distillate is crystallized from 2,2'-oxybispropane. The product is filtered off and dried, yielding 25 parts of 3-(4-bromophenyl)-1,2-propanediol; mp. 60.6° C.
