Abstract Treatment of the hydroxyquinoline-3-carbonitriles 6a,b;24 and 29,respectively. The 4-azidoquinoline-3-carbonitriles 8,25 and the 5-azido-tetrazolo[1,5-a]quinoline-4-carbonitriles 17a,b were prepared by reacting 6a,24 and 7a,b with sodium azide in DMF,respectively. The phosphazenes compounds 11; 18a,b; 19and 26 were obtained ,in good yields, by reacting the corresponding azides 8; 17a,b;17a and25 with triphenylphosphine, respectively. The acid hydrolysis of these phosphzenes yielded the corresponding amines 14; 20a,b;21 and 27,respectively. The 5-amino-tetrazolo[1,5-a]quinoline-4-carbonitrile21 is converted into 2,4-dia,ino-quinoline-4-carbonitrile 21 is converted into 2,4-diamino-quinoline-4-carbonitrile 20a by reacting it with triphenylphine to yield the intermediate 22 wich undergoes acid hydrolysis to yield 20a. |
