Abstract
326,398. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 2, 1929. Nitro derivatives of 2 : 4-dihydroxyquinoline and N-substituted - 1 : 2 - dihydro - 4 - hydroxy-2-ketoquinolines are obtained by treatment with nitric acid in sulphuric acid. The new nitro compounds differ from those previously known, in that they may be combined with diazo compounds to give dyestuffs, and mav be reduced to amino compounds suitable for azo dyestuffs. The corresponding sulphonated nitro and amino derivatives are valuable intermediates. In examples, (1) 2 : 4- dihydroxyquinoline is nitrated with a mixture of sulphuric and nitric acids; (2) N-methyl-1 : 2- dihydro - 4 - hydroxy-2-ketoquinoline is nitrated similarly; N-ethyl-, N-phenyl-, and like derivatives of 1 : 2-dihdro-4-hydroxy-2-ketoquinoline may be nitrated in a similar manner.
