الإجراء التجريبي

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-fluoroethoxy)piperidin-1-yl)-4-methyl-1,3-thiazole-5-carboxylate obtained in Example (124a) (0.24 g, 0.49 mmol), 2 N lithium hydroxide (4 mL, 8 mmol), methanol (6 mL) and THF (6 mL), to obtain 0.21 g of the title compound as a light brown solid (93%).
