Reaction Steps

In 100 ml of absolute ethanol, 8.35 g of the compound of Example II was hydrogenated over 2 spatulas-full of 10% Pd/C in a Parr apparatus at ca 40 lbs/in2 for 3-4 hrs. Under a nitrogen blanket, the catalyst was filtered off through a Celite pad (sintered glass funnel), which was washed with two volumes of ethanol. Evaporation gave ca 7.2 g of a brown oil.
