実験手順

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer was charged with 318a (200 mg, 1.0 eq., 0.32 mmol), lithium hydroxide (38 mg, 5.0 eq., 1.60 mmol), i-propanol/THF (8/8 mL), and water (2 mL). The mixture was stirred at room temperature for 1 h and concentrated under reduced pressure. The residue was added partitioned between water and dichloromethane. The combined organic layer was concentrated under reduced pressure. The residue was purified by reverse-phase prep-HPLC to afford racemic mixture 318b as a yellow solid (91 mg, 43%).
