| titleOfInvention | Preparation of 2(2,6-dichloroanilino)phenyl acetic acid |
| abstract | PURPOSE: To prepare the title compound useful as an antiphlogistic, analgesic, and antipyretic in a simple process in high yield, by treating an alkali salt of 2-(2,6- dichloroanilino)-phenylpyruric acid with a mineral acid. n CONSTITUTION: A novel compound of formulaII: (R is lower alkyl, preferably methyl or ethyl group) is hydrolyzed in an alcoholic alkali hydroxide, preferably KOH or NaOH, to give a compound of formulaI: (M is alkali metal, preferably K or Na), which is treated with one or more types of mineral acids, preferably hydrochloric, sulfuric, or nitric acid, to form the desired 2-(2,6-dichloroanilino)- phenylacetic acid of formulaIII. The compound of formulaII can be readily obtained by reacting 2-(2,6-dichloroanilino)-benzaldehyde with a compound of formulaIV to form a compound of formulaV, which is oxidized. n COPYRIGHT: (C)1980,JPO&Japio |
