実験手順
Compound 125 (110 mg, 0.19 mmol) obtained in Example 124, Step 3 was dissolved in methanol (1.0 mL), and a 10% solution of hydrogen chloride in methanol (1.5 mL, 3.5 mmol) was added thereto with stirring under ice-cooling. The reaction mixture was stirred at room temperature for 30 minutes, and concentrated under reduced pressure. The resulting residue was crystallized from ethanol to obtain Compound 139 (106 mg, 89%).
