실험 절차

The product of Example 457A (0.452 g, 1.67 mmol) in tetrahydrofuran (20 mL) was treated with ammonium formate (0.30 g, 5.01 mmol) and a catalytic amount of 20% palladium hydroxide on carbon at 60° C. for 2 hours. The reaction was filtered through diatomaceous earth and the filtrate concentrated under reduced pressure to provide the title compound (0.30 g, 100%).
