2- Hydrazinocinconic acid

The tetrazoloquinoline such as 789 are readily prepared by reaction of 2-hydrazinocinconic acid 788 with nitrous acid (91KG1227). Reaction of 790 with hydrazine introduces hydrazine residues at positions 2, 6 and 7 whose reaction with nitrous acid gave 791 (90M1017) (Scheme 139). [Pg.175]
