Methanol → cis(+/-)-2-(4-{[(4-Chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-(2-fluoroethoxy)piperidin-1-yl)-1,3-thiazole-5-carboxylic acid

Participants

Reaction Steps

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)-1,3-thiazole-5-carboxylate obtained in Example (123f) (0.25 g, 0.8 mmol), 2 N lithium hydroxide (3 mL, 6 mmol), methanol (8 mL) and THF (8 mL), to obtain 0.17 g of the title compound as a light brown solid (72%).
