Versuchsvorschrift

To a solution of 5.84 g (20 mmol) of Compound 10 in 50 mL ethyl acetate and 30 mL methanol, 100 mg of 10% Pd/C was added, and the mixture was hydrogenated at 30 psi for 6 h. The catalyst was removed by filtration through a pad of Celite, the solvent was evaporated to dryness resulting in a dark purple solid which was recrystallized from ether-hexane. The mother liquid was evaporated, and the resulting solid was suspended in hexane and filtered to give additional yield of Compound 11
