Lithium hydroxide, monohydrate → HCID 58305674, compound

Participants

Reaction Steps

To a solution of ethyl 3-(1-(4-carbamoyl-2-methylphenyl)-5-(4-(methylsulfonyl)phenyl)-1H-pyrrol-2-yl)propanoate (28C) (100 mg, 0.22 mmol) in THF/H2O (v/v=1/1, 1 mL) was added lithium hydroxide monohydrate (18 mg, 0.44 mmol) and stirred overnight at room temperature. THF was evaporated in vacuum and the resulting aqueous solution was acidified with 10% hydrochloric acid to pH=4.0. The resulting precipitate was separated by centrifuge, rinsed with distilled water and purified by prep-HPLC to afford 3-(1-(4-carbamoyl-2-methylphenyl)-5-(4-(methylsulfonyl)phenyl)-1H-pyrrol-2-yl)propanoic acid (28D) as a light green solid (30 mg, 32%).
