| titleOfInvention | Novel o-nitrobenzoic acid derivative and its preparation |
| abstract | NEW MATERIAL:The o-nitrobenzoic acid derivative of formulaI(R 1 and R 3 are lower alkyl; R 2 is straight or branched chain alkoxycarbonyl; R 1 WR 3 bond to the 3W5-positions or 4W6 positions in this order). n EXAMPLE: 4-Ethoxycarbonyl-3,5-dimethyl-2-nitrobenzoic acid. n USE: Intermediate of 6-alkoxycarbonyl-5,7-dialkyl-3-phenyl-2(1H)-quinoxalinone derivative, etc. useful as a remedy for hypertension, ischemic cardiopathy, and ischemic cerebrovascular disorder. n PROCESS: The compound of formulaIis prepared by oxidizing the anthranilic acid derivative of formula II with hydrogen peroxide preferably in the presence of maleic anhydride. n COPYRIGHT: (C)1982,JPO&Japio |
