A solution of 7-bromo-4-quinazolinone (2.6 g) in 5 mL of concentrated H2SO4 and 5 mL of fuming HNO3 was heated at 100° C. for 1 h. After the reaction was cooled to room temperature, the mixture was poured into ice-water. The solid was collected via filtration, and used without further purification, 7-bromo-6-nitro-4-quinazolinone (mixed with 7-bromo-8-nitro-4-quinazolinone, LCMS ESI(+) m/z: 270/271 (M+1).
