실험 절차

A mixture of the product of Step A (1.48 g) and 1,4-cyclohexadiene (6.2 mL) and palladium (10% wt on activated carbon) (1.4 g) in ethanol (100 mL) was stirred at reflux temperature for 2 hours and cooled to ambient temperature and stirred for 12 hours. The reaction mixture was filtered through a pad of celite and the celite pad rinsed with ethanol (100 mL) and methanol (100 mL). The filtrate was collected and evaporated to yield the title compound (710 mg).
