Synthesis, crystallographic studies and biological evaluation of some 2-substituted 3-indazolyl-4(3H)-quinazolinones and 3-indazolyl-4(3H)-benzotriazinones
A number of new 3-(indazol-3 and 5-yl)-4(3H)-quinazolinone and 4(3H)-benzotriazinone derivatives were prepared by reaction of 3- or 5-(2-aminobenzamido)indazole with ethyl orthoesters and nitrous acid respectively. Structures were established on the basis
