실험 절차
A mixture of intermediate A (1 g, 6 mmole), 1,3-cyclohexadiene (0.6 ml, 6 mmole), and toluene (15 ml) was refluxed about 15 hours under a nitrogen atmosphere. The solvent was removed under reduced pressure to yield 1.5 g of crude Diels-Alder adduct (intermediate B), which was used directly in the next step.
