Procedure

To a mixture of methyl 7-hydroxy-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxylate (400 mg), 3-propoxyphenylboric acid (536 mg), cupric acetate (271 mg), MS 4A (0.8 g) and dichloromethane (15 ml) was added at room temperature triethylamine (1.04 ml), and the resulting mixture was stirred for 17 hours. The reaction mixture was filtered to remove an insoluble material and the filtrate was concentrated under reduced pressure. The residue was subjected to separation and purification using column chromatography (ethyl acetate:hexane 1:2) to obtain methyl 7-(3-propoxyphenoxy)-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxylate (0.39 g) as a light yellow, oily substance.
