Participants

Reaction Steps

The product from Example 212b (0.0795 g, 0.309 mmol) was dissolved in ethanol (2 mL) and to this solution was added Pt(IV) oxide (5.2 mg). The reaction mixture was vacuum degassed then exposed to one atmosphere of hydrogen for 3 h at room temperature. The catalyst was removed by filtration through celite and the filtrate concentrated under vacuum to give the title compound in quantitative yield.
