Participants

Reaction Steps

To a solution of methyl 2-(4-fluoro-2-methylphenyl)-3-(isopropyl(methyl)amino)quinoxaline-6-carboxylate (45 mg, 0.12 mmol) in methanol (35 mL) and water (2.0 mL) was added sodium hydroxide (20 mg, 0.50 mmol) and the reaction was stirred overnight at room temperature. The reaction mixture was concentrated in vacuo, dissolved in water (20 mL) and adjusted to pH 4 with aqueous HCl (3N). The solids were collected by filtration to afford 2-(4-fluoro-2-methylphenyl)-3-(isopropyl(methyl)amino)quinoxaline-6-carboxylic acid as a light yellow solid (36 mg, 83%).
