실험 절차

Ethyl cis(±)-2-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl)-4-formyl-1,3-thiazole-5-carboxylate obtained by the method described in Example (28a) (100 mg, 0.21 mmol) was dissolved in pyridine (3 mL). Methoxyamine hydrochloride (28 mg, 0.34 mmol) was added, and the mixture was stirred at 60° C. for two hours. The reaction solution was concentrated under reduced pressure, diluted with ethyl acetate, washed with 1 N hydrochloric acid and brine, and dried over anhydrous sodium sulfate. Following concentration under reduced pressure, the residue was purified by silica gel column chromatography (elution solvent: hexane/ethyl acetate=4/1, ethyl acetate) to obtain 107 mg of the title compound (100%).
