Versuchsvorschrift

The chloroquinolone (7a) in dry DMF (8 mL) was cooled in ice and phosphorus tribromide (0.7 mL) added drop-wise, and the mixture was stirred, with ice-cooling for 30 minutes then allowed to warm to room temperature and stirred for a further 2 hours. It was cooled in ice and sodium carbonate solution was added and the solid was collected, washed well with water, and dried in vacuo, to afford a pale yellow solid (1.65 g).
