実験手順
Compound 55 (0.772 g, 0.002 mole) in 20 ml of 10% NaOH solution was heated under refluxing for 2 h, cooled and acidified with 10% HCl solution in an icewater bath. The precipitates were collected, then recrystallized from ethanol to afford compound 59 (0.595 g). Yield 80.2%; white crystals; mp 243-244° C.
