실험 절차
20 mL of water and 20 mL of concentrated hydrochloric acid were added to the product of Example 38 (2.5 g, 8 mmol), then it was reacted at 80° C. for 17 hours, after that, the reaction solution was concentrated and recrystallized with isopropanol and isopropyl ether to give the target 1.9 g, yield: 90%. The HNMR spectrum data is the same as that in Example 7.
