Hydrochloric Acid → (4'-{1-ethyl-1-[4-(3-hydroxy-4,4-dimethyl-pentyl)-3-methyl-phenyl]-propyl}-3-fluoro-2'-methyl-biphenyl-4-yl)-acetic Acid

Participants

Reaction Steps

A mixed solution of a 6 N sodium hydroxide aqueous solution (0.011 mL) with water (0.032 mL) was added to a solution of (4′-{1-ethyl-1-[4-(3-hydroxy-4,4-dimethyl-pentyl)-3-methyl-phenyl]-propyl}-3-fluoro-2′-methyl-biphenyl-4-yl)acetic acid methyl ester (Example 60-(2); 8.5 mg, 0.016 mmol) in methanol (0.22 mL) at room temperature, and the mixture was stirred at room temperature for six hours. The mixture was acidified with dilute hydrochloric acid aqueous solution, followed by extraction with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to give the title compound (8 mg, 100%).
