Versuchsvorschrift

To a Parr bottle charged with a mixture of platinum (IV) oxide (30 mg) in ethanol (3 mL) was added a solution of the product of Step A (90 mg) in methanol (6 ml). The mixture was hydrogenated at 40 psi for 4 hours and filtered through a Celite pad which was rinsed with several additional milliliters of methanol and ethanol. The filtrate was collected and evaporated in vacuo to yield the title compound (88 mg) which was used without further purification.
