A stirred solution of tributyl-(7-[1,3]dioxan-2-yl-benzofuran-5-yl)stannane (9.6 g), lead tetraacetate (9.8 g) and mercuric acetate (350 mg) in chloroform (200 ml) was heated at 45° for 20 h. The mixture was cooled and filtered through Hyflo. The filtrate was evaporated to dryness. The residual gum was triturated under hexane (200 ml) for 2 h to give the title compound as an off-white solid (9.4 g), m.p. 92-94°.
