실험 절차

The same operation as in Example (91d) was performed using ethyl cis(±)-2-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-(2,2-difluoroethoxy)piperidin-1-yl)-1,3-thiazole-5-carboxylate obtained in Example (121g) (0.12 g, 0.24 mmol), 2 N lithium hydroxide (3 mL, 6 mmol), methanol (4 mL) and THF (4 mL), to obtain 90 mg of the title compound as a colorless solid (80%).
