Procedure

To a stirred solution of 38 parts of 2-(2-nitrophenoxymethyl)-oxirane in 10 parts of ethanedioic acid and 300 parts of 1,4-dioxane are added 100 parts of water. The whole is stirred and refluxed for 2 days. The reaction mixture is evaporated and the residue is crystallized from a mixture of 2,2'-oxybispropane and petroleumether. The product is filtered off and recrystallized from 2,2'-oxybispropane, yielding 29.5 parts (13%) of 3-(2-nitrophenoxy)-1,2-propanediol; mp. 96° C..
