Reaction Steps

The product obtained using Compound 18 (300 mg, 0.90 mmol), 2-(tert-butoxycarbonyl)amino-2-methylpropionic acid (153 mg, 0.75 mmol), 1-hydroxybenzotriazole monohydrate (132 mg, 0.98 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (202 mg, 1.05 mmol) and N-methylmorpholine (0.16 mL, 1.50 mmol) in a similar manner to Example 5, was dissolved in methanol (2.00 mL), and the solution was added with 4 mol/L hydrogen chloride-methanol solution (1.50 mL), followed by heating under reflux at 60° C. for 30 minutes. The reaction mixture was concentrated under reduced pressure, and the residue was crystallized from acetone to obtain Compound 131 (0.10 mg, 23%).
