Reaction Steps

3.50 g (17.7 mmol) of the product from example 49A are dissolved in 30 ml of ethanol and admixed with 2.00 g of 10% palladium on activated carbon. Hydrogenation is effected overnight in a hydrogen atmosphere under standard pressure. The mixture is filtered with suction, washed with ethanol and concentrated cautiously under reduced pressure. This affords 1.9 g of approx. 89% pure product (69% of theory), which is converted further without purification.
