    • A solution of 5 (1.3 mmol) in dry dioxane (20 mL) was treated with silver carbonate (1.76 g, 6.5 mmol) and warmed to 50 °C in the dark under a nitrogen atmosphere for 24 h. The residue was filtered off, the solvent evaporated under reduced pressure and the residue was chromatographed on a silica gel column with ethyl acetate-hexane 3:7 to give 7.
