実験手順
The compound (1.38 g) obtained in Example 77-1 was dissolved in methanol (10 ml) and then added with a 4 mol/l hydrogen chloride/dioxane solution (15 ml), followed by stirring at room temperature for 30 minutes. The reaction solution was concentrated under reduced pressure and added with anion-exchange resin (Amberlite IRA-410) in methanol to adjust the solution to pH 8. After the resin had been removed through filtration, the solvent was distilled off, thereby obtaining the subject compound (0.79 g) as a yellow solid.
