Reaction Steps

The product obtained using dihydrochloride of Compound 18 (100 mg, 0.25 mmol), N-(tert-butoxycarbonyl)-L-proline (53 mg, 0.25 mmol), 1-hydroxybenzotriazole monohydrate (43 mg, 0.33 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (66 mg, 0.35 mmol) and N-methylmorpholine (0.06 mL, 0.50 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 added with saturated sodium hydrogencarbonate solution and ethyl acetate, followed by extraction. The crude product was crystallized from acetone to obtain Compound 140 (21 mg, 20%).
