実験手順

The product (217) (2.46 g, 5.3 mmol) and KOH (2.5 g, 45 mmol) is dissolved in EtOH (20 mL) and water (1 mL) under a water bath. The water bath is removed when the 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 (50 mL) and acidified with conc. HCl until no more white precipitate came out of the water. The precipitate is filtered to give a pure product (218) as white solid (1.4 g, 61%).
