実験手順

0.50 g of 13a was dissolved in 25 ml of solvent mixture that consists of THF and methanol (v/v=7/3) and stirred with 0.30 g of palladium (10% on magnesium carbonate) for 3.75 hours at room temperature under hydrogen atmosphere. Then, the reaction solution was filtered on Celite, the filtrate was evaporated to the dry state in a rotary evaporator and the bright foam that was obtained was used without additional purification in the next stage.
