실험 절차
A solution of 5.9 g of the compound obtained in Step 2 in 150 ml of ethanol was hydrogenated for 12 hours in the presence of 0.6 g of Raney nickel (10% w/w) under a hydrogen gas pressure of 60 psi. After the reaction was completed, the reaction solution was filtered with Celite® 545 and the filtrate was concentrated under reduced pressure. To the residue thus obtained was added 150 ml of toluene, and the resulting mixture was heated to reflux for 2 hours. The reaction product solution was concentrated under reduced pressure, and the residue thus obtained was purified by a silica gel column chromatography using a mixture of ethyl acetate and methanol of 9:1 to obtain 3.35 g of the title compound as a white solid.
