実験手順

To a solution of 3-methyl-4-[2-[N-(5-methyl-2-furylsulfonyl)amino]4,5-dimethylphenoxymethyl]benzoic acid methyl ester prepared in Reference Example 3 (870 mg) in N,N-dimethylacetamide (2 ml), cesium carbonate (1.37 g) and isobutyl iodide (0.36 ml) were added and the mixture was stirred for 1 hour at 100° C. The reaction mixture was allowed to cool and poured into ethyl acetate-water (40 ml-40 ml). The organic layer was washed, dried and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (toluene-ethyl acetate) to give the title compound (855 mg) having the following physical data.
