Reaction Steps

2.20 g (9.49 mmol) of silver(I) oxide are added in portions, over a period of 48 hours, to a solution of the compound obtained in Example 31 (0.52 g; 1.45 mmol) in 5 ml of dioxane. The reaction mixture is then filtered and the filtrate is evaporated to give 0.32 g (1.39 mmol) of the desired product in the form of a white solid.
