Hydrochloric Acid → (4-Chloro-7-fluoro-6-((1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)methoxy)-1-benzothiophen-3-yl)acetic acid

Participants

Reaction Steps

To a mixture of methyl(4-chloro-7-fluoro-6-((1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)methoxy)-1-benzothiophen-3-yl)acetate (133 mg), THF (dry) (2.0 mL) and MeOH (2.0 mL) was added 1N NaOH (0.913 mL) at room temperature. The mixture was stirred at room temperature for 2 h. The mixture was neutralized with 1N HCl. The resulting precipitate was collected by filtration to give a solid. The solid was crystallized from EtOAc-hexane to give the title compound (114 mg).
