실험 절차

A suspension of 0.5 g (1.245 mmol) of 165 and 0.25 g of palladium (10 wt % on activated carbon) in 60 mL of methanol was stirred at room temperature under hydrogen gas atmosphere for 24 h. The precipitate were collected and dissolved in 10% NaOH solution and then filtered. The filtrate was acidified with dil aq HCl and the precipitate was then collected and washed with acetone and water to give 166.
