摘要

Compound IVb (128 mg, 0.92 m mol) was dissolved in 25 ml of 95% ethanol, and 20 mg of 10% palladium on carbon was added. The mixture was placed under 1 atm of hydrogen and stirred magnetically as hydrogen was absorbed. After an induction period of 12 min, 1 mol of hydrogen was taken up in 24 min and 2 mol at a distinctly slower rate in 2.5 hr. The hydrogen uptake stopped and the catalyst was removed. Removal of the solvent on a ...
