実験手順

The 5-bromo-N-(5-chlorothiazol-2-yl)spiro[indoline-3,3′-pyrrolidine]-1-carboxamide (160 mg, 0.387 mmol) obtained in Example 2 was dissolved in N,N′-dimethylformamide (4.0 mL). Thereafter, formic acid (22.0 μL, 0.581 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (148 mg, 0.774 mmol) were added to the above obtained solution, and the thus obtained mixture was then stirred for 18 hours. Thereafter, the reaction solution was diluted with water, and was then extracted with ethyl acetate. The organic layer was washed with brine, and was then dried over anhydrous sodium sulfate, followed by concentration in vacuo. The obtained residue was purified by silica gel column chromatography (chloroform:methanol=20:1) to obtain the captioned compound (92.8 mg, 54%) in the form of a white solid.
