실험 절차

The product of Example 2 (2.0 g) and 10% Pd/C (350 mg) in DMF (20 mL) were shaken at 55 psi hydrogen for 3 hours. The catalyst was removed by filtration and the filtrate was concentrated under vacuum to yield a yellow wax. The wax was triturated with methanol and the resulting amber solid was collected by filtration to afford the title compound (1.6 g).
