Sulfuric Acid → 5-Bromo-8-nitroquinoline

Participants

Reaction Steps

KNO3 (1.58 g, 15.6 mmol) was added portionwise to a solution of 5-bromoquinoline (2.0 g, 12.0 mmol) conc.H2SO4 (7.5 ml) at 0° C. and the mixture was stirred at room temperature for 16 h. The mixture was poured onto ice and the resulting solid was extracted into DCM. The organic phase was washed with brine, dried (Na2SO4) and concentrated in vacuo to give the title compound (2.8 g, 92%) which was used in the next step without further purification.
