Convenient Preparation of N-substituted 2-Amino-4H-3,1-benzoxazin-4-ones and 3-Substituted 2,4(1H,3H)-Quinazolinediones

Room temperature of 2-(3-arylureido)benzoic acids (1) and methyl2-(3-alkyl-, or 3-arylureido)-benzoates (2) with concentrated sulfuric acid leads to N-substituted 2-amino-4H-3,1-benzoxazin-4-ones (3) in generally very good yields.The isomeric 3-substitute
