Participants

Reaction Steps

To a solution of methyl 2-(1H-indol-5-yl)-3-[(2R)-2-(methoxymethyl)pyrrolidin-1-yl]quinoxaline-6-carboxylate (200 mg, 0.48 mmol) in methanol (35.0 mL) and water (1.0 mL) was added sodium hydroxide (76.9 mg, 1.92 mmol) with stirring overnight at room temperature. The reaction mixture was concentrated in vacuo, dissolved in water (30.0 mL), adjusted pH to 4 with HCl (3N) to give the precipitate, which was collected by filtration to afford 2-(1H-indol-5-yl)-3-[(2R)-2-(methoxymethyl)pyrrolidin-1-yl]quinoxaline-6-carboxylic acid (80 mg, 41%).
