| titleOfInvention | Preparation of anthranylic acid derivative |
| abstract | PURPOSE: To produce the titled compound useful as a medicine, easily, in high yield and purity, by reacting a reactive derivative of 3,4-dimethoxycinnamic acid with isatin, and hydrolyzing the resultant novel compound in the presence of an oxidizing agent without separating from the reaction mixture. n CONSTITUTION: The objective N-(3,4-dimethoxycinnamoyl)anthranylic acid of formula IV and its salt can be prepared by reacting a reactive derivative of 3,4-dimethoxycinnamic acid of formula I with isatin of formula II, and hydrolyzing the resultant novel N-(3,4-dimethoxycinnamoyl)isatin of formula III in the presence of an oxidizing agent (e.g. hydrogen peroxide). As an alternative method, the compound of formula IV is obtained by hydrolyzing the compound of formula III without using an oxidizing agent, and oxidizing the resultant novel compound of formula V. n COPYRIGHT: (C)1986,JPO&Japio |
