Procedure
The compound (83.0 mg) obtained in Example 18-4 was dissolved in methanol (1.0 ml) and added with a 4 mol/l hydrogen chloride/dioxane solution (1.0 ml) and the whole was stirred at room temperature for 6 hours. After completion of the reaction, the solvent was distilled off under reduced pressure. The residue was dissolved in methanol to generate a free compound therefrom through an anion-exchange resin (Amberlite IRA-410). The resin was separated by filtration and the filtrate subjected to distillation of the solvent under reduced pressure. The residue was purified through silica gel column chromatography (chloroform/ethyl acetate), thereby obtaining the subject compound (44.0 mg) as a brown solid.
