Reaction Steps

Under nitrogen atmosphere, palladium-activated carbon (10% Pd, 0.30 g) was added to a solution of 2.75 g of the compound obtained in Step 78-1 in EtOH (30 ml) and the inside of the reaction system was displaced with hydrogen gas. The solution was stirred at room temperature for two hours, then, the reaction solution was filtered, and the solvent was filtered out under reduced pressure to obtain 1.97 g of residue (pale yellow oil). The present compound was used in the next reaction without purification.
