실험 절차
200 mL tetrahydrofuran, 6-(4-nitro-phenyl)-hexane-2,4-dione (8.0 g, 34.0 mmol) and dihydro-pyran-2,6-dione (3.88 g, 34.0 mmol) were added to a reaction vessel. The reaction vessel was purged three times with argon. Approximately 200 mg palladium (10 wt % on activated carbon) was added. The reaction vessel was purged again with argon and excess hydrogen introduced via a balloon. Solution stirred 16 hours at room temperature. Hydrogen removed under reduced pressure and catalyst removed by filtration through celite. Tetrahydrofuran removed under reduced pressure to afford title compound (10.5 g, 97%, yellow solid).
