2-Methyl-3-substituted-3, 4-dihydro-4-oxo-quinazoline were obtained by one-step reaction of N-acetyl-anthranilic acid with various aromatic amines in polyphosphoric acid. In order to synthesize biologically active 4-quinazolone derivatives and to establish the structure of nitration products of 2-methyl-3-phenyl-4-quinazolone several nitro derivatives of 2-methyl-3-phenyl-3, 4-dihydro-4-oxo-quinazoline were prepared. It was found that nitro group was introduced in meta position in 3-phenyl group and in 6-position in 4-quinazolone.N-アセチルアンスラニル酸と種々の芳香族アミンとをポリリン酸中で加熱縮合させると,容易に一段階反応により2-メチル-3-置換-3.4-ジヒドロ-4-オキソーキナゾロン誘導体が得られることが判った。さらにこの反応はN-アセルアンスラニル酸のニトロ誘導体,芳香族アミンのニトロ化合物を用いても容易に進行して相応するニトロ化合物を与えた。2-メチル-3-フエニル-4-キナゾロンを混酸でニトロ化して得られるジニトロ化合物は3-フエニル...
