実験手順

To the solution of 4-methoxybenzyl 5-chloro-1-ethyl-6,7-bis((4-methoxybenzyl)oxy)-4-oxo-1,4-dihydrocinnoline-3-carboxylate (24 g, 37.2 mmol) in methanol (400 mL) and water (133 mL) was added potassium hydroxide (8.35 g, 149 mmol). The reaction mixture was heated to reflux for 3 h. Solvent was removed under vacuum. The residue was suspended in water and the resulting mixture was acidified to pH4 with 2N hydrochloric acid. The precipitated solid was filtered and dried to afford 5-chloro-1-ethyl-6,7-bis((4-methoxybenzyl)oxy)-4-oxo-1,4-dihydrocinnoline-3-carboxylic acid (12.6 g, 24.00 mmol, 64.5% yield). LCMS: (M+H)+: 525.2
