Methanol → cis(+/-)-2-(4-{[(4-Chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-propoxypiperidin-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-propoxypiperidin-1-yl)-1,3-thiazole-5-carboxylate obtained in Example (126b) (0.27 g, 0.59 mmol), 2 N lithium hydroxide (5 mL, 10 mmol), methanol (5 mL) and THF (5 mL), to obtain 0.22 g of the title compound as a colorless solid (87%).
