反応手順

The product (220) and KOH (1.0 g, 18 mmol) is dissolved in EtOH (8 mL) and water (1 mL) under a water bath. The water bath is removed when KOH is completely dissolved and the resulting reaction solution is stirred at RT for 3 h. After concentration in vacuo, the residue is dissolved in water (20 mL) and acidified with conc. HCl until no more white precipitate formed. After the filtration, the obtained brown solid is purified by HPLC to give pure product (221) as white solid (200 mg, 62%).
