Procedure

The product obtained using (E)-4-[2-(1H-indazol-3-yl)vinyl]benzoic acid (700 mg, 2.65 mmol) obtained in Step 6 of Example 1, (S)-(pyrrolidin-3-yl)carbamic acid tert-butyl ester (740 g, 3.98 mmol), 1-hydroxybenzotriazole monohydrate (470 mg, 3.46 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (710 mg, 3.72 mmol) and N-methylmorpholine (0.608 mL, 5.32 mmol) in a similar manner to Example 5, was dissolved in methanol (1.5 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 60 minutes. The reaction mixture was concentrated under reduced pressure, and the residue was added with saturated aqueous sodium hydrogencarbonate solution and ethyl acetate, followed by extraction. The crude product was crystallized from acetone to obtain Compound 159 (190 mg, 22%).
