Sodium Hydroxide → HCID 68194182, compound

Participants

Reaction Steps

Sodium hydroxide (52.0 mg, 1.30 mmol) was added to a solution of methyl 3-(7-fluoro-1,2,3,4-tetrahydroquinolin-1-yl)-2-(4-fluorophenyl)quinoxaline-6-carboxylate (140 mg, 0.32 mmol) in methanol (30 mL) and water (1.0 mL). The reaction was stirred overnight at room temperature and then concentrated in vacuo, dissolved in water (30 mL), and adjusted to pH 5 with aqueous hydrochloric acid (3 N) to give a precipitate, which was collected by filtration to afford 3-(7-fluoro-1,2,3,4-tetrahydroquinolin-1-yl)-2-(4-fluorophenyl)quinoxaline-6-carboxylic acid as a light yellow solid (100 mg, 74%).
