Procedure

Concentrated hydrochloric acid (50 ml) was added to the product of Example 3 (8.4 g) and stirred for 20 hours at room temperature. The reaction mixture was poured into a solution of water (50 ml) containing sodium chloride and extracted three times with 75 ml of diethyl ether. The combined diethyl ether extracts were dried over anhydrous magnesium sulfate, filtered and concentrated to an oil with a rotary evaporator. The product was purified by silica gel chromatography, and the structure was supported by NMR spectroscopy. The NMR spectrum showed a small amount of the cis-product as well.
