Reaction Steps

Compound 3 was suspended in AcOEt and placed under nitrogen atmosphere; then 10% palladium on carbon (catalytic amount) was added. The reaction mixture was placed under vacuum for a few min then opened up under a balloon of hydrogen and stirred at ambient temperature for 18 h. The reaction mixture was filtered through Celite® and concentrated to give compound 4 (0.393 g, 95% yield).
