Lithium Hydroxide → cis(+/-)-2-(4-{[(4-Chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-(3-fluoropropoxy)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-(3-fluoropropoxy)piperidin-1-yl)-1,3-thiazole-5-carboxylate obtained in Example (127f) (0.16 g, 0.8 mmol), 2 N lithium hydroxide (6 mL, 12 mmol) and methanol (5 mL), to obtain 0.13 g of the title compound as a light brown solid (88%).
