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)-4-methyl-1,3-thiazole-5-carboxylate obtained in Example (122a) (0.24 g, 0.48 mmol), 2 N lithium hydroxide (3 mL, 6 mmol), methanol (3 mL) and THF (8 mL) to obtain 0.16 g of the title compound as a colorless solid (71%).
