The alcohol of Example 3 (800 mg) was added to pyridine (20 ml) and acetic anhydride (5 ml) and the mixture was stirred at room temperature over two days. The mixture was then evaporated down under vacuum and the residue was dissolved in diethyl ether. The solution was decolourised over charcoal, and the ether was removed to give 860 mg of the desired product. NMR showed that the product was a mixture of geometric isomers.
