2-Phenylamino-6,8-dibromo-4H-3,1-benzoxazinone has been reacted with nitrogen nucleophiles, such as hydrazine hydrate, amines, and formamide, yielding 4(3H)quinazolinone derivatives; and with sulfur nucleophiles producing the corresponding thioesters. The behavior of aminoquinazolinone and 4(3H)quinazolinone towards some carbon electrophiles under different conditions has been studied.
