실험 절차

This quinolone (410 mg, 1.6 mmol) in POCl3 (5 mL) was refluxed for 2 h, then poured onto ice. The solution was neutralized to pH 7 by addition of NH4OH, and the resulting solid collected by filtration. Washing with water and drying in vacuo gave 6-bromo-2-chloro-4,8-dimethyl-quinoline (407 mg, 93%).
