A process for the production of aminophthalides and amino benzoic acids
摘要:
Process comprises the combination of the two steps of condensing Y-benzaldehyde with NR 2 R 3- aniline and 3-NRR 1 - benzoic acid, under acidic conditions to produce 2-[Y-phenyl) (4-NR 2 R 3 -aminophenyl)methyl]-5-NRR 1 -aminobenzoic acid, and oxidizing said benzoic acid to produce 3-(Y-phenyl)-3-(4-NR 2 R 3- aminophenyl)-6-NRR 1 -aminophthalide.
