Procedure

5 g of boron tribromide are added dropwise to a solution, cooled to -78° C., of 2 g of methyl N-(3-methoxyphenyl)-oxamate in 20 ml of methylene chloride in the course of 5 minutes. The mixture is stirred at room temperature for 5 hours, 5 ml of water are added, with cooling, and the organic phase is separated off. Drying over sodium sulfate and evaporation gives methyl N-(3-hydroxyphenyl)-oxamate.
