Procedure

To a dried methanol solution (100 ml) of 3-(2',4'-dichloro-5'-methoxycarbonyloxyphenyl)-5-isopropylidene-1,3-oxazolidine-2,4-dione (3.60 g, 10 mmol), which was synthesized from 2,4-dichloro-5-methoxycarbonyloxy nitrobenzene as a starting material in a method similar to that shown in Reference Example 6, 9, 10 and 4, was added potassium carbonate (0.69 g, 5 mmol) and the mixture was heated under reflux for 2 hours. 3-(2',4'-dichloro-5'-hydroxyphenyl)-5-isopropylidene-1,3-oxazolidine-2,4-dione (1.72 g) was obtained by a treatment similar to that in Reference Example 1.
