実験手順

Methyl 7-hydroxy-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxylate (400 mg), 3-(2-propoxyphenyl)propyl methanesulfonate (1.06 g) and potassium carbonate (309 mg) were suspended in DMF (15 ml), and the resulting suspension was stirred at 60° C. for 3 hours. The reaction mixture was diluted with ethyl acetate and was washed respectively with water and an aqueous saturated solution of sodium chloride, and the organic layer was dried with anhydrous magnesium sulfate. After concentration under reduced pressure to remove the solvent, the residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:1) to obtain methyl 7-[3-(2-propoxyphenyl)propoxy]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxylate (832 mg) as a yellow oil.
