Hydrochloric Acid → HCID 70665309, compound

Participants

Reaction Steps

To a solution of methyl 2-(4-fluorophenyl)-3-(pyrrolidin-1-yl)quinoxaline-6-carboxylate (72 mg, 0.20 mmol) in methanol (20 mL) was added sodium hydroxide (50 mg, 1.25 mmol). After stirring overnight at room temperature, the reaction mixture was concentrated under reduced pressure to afford a residue, which was dissolved in water (10 mL), adjusted to pH 6 with hydrochloric acid (3N). The product formed a precipitate and was filtered to give 2-(4-fluorophenyl)-3-(pyrrolidin-1-yl)quinoxaline-6-carboxylic acid as a light yellow solid (41.5 mg, 60%).
