Procedure

Under atmosphere of argon, a mixture of 2-nitro-4,5-dimethylphenol (4 g), DMF (100 ml), potassium carbonate (6.6 g) and 4-mesyloxymethyl-3-methylbenzoic acid methyl ester (6.8 g) were stirred for 15 minutes at 60° C. After the termination of reaction, the mixture was cooled and poured into iced water. The mixture was extracted with ethyl acetate-hexane. The organic layer was washed, dried, concentrated under reduced pressure to give the title compound (7.22 g) having the following physical data.
