## Abstract magnified image Synthesis of novel 3โsubstitutedโ1,2,3โtriazolo[1,5โa]quinazolinones in high yields was performed __via__ anionic heteroโdomino reaction of appropriate substituted 2โazidobenzoates prepared from isatines and acetonitriles activated by 1,3โthiazole, 1,3โbenzothiazole, 1,3
With sodium borohydride in tetrahydrofuran/ethanol (5 : 1). the product ( I ) gives a 75 yield of a compound, m.p. 233 "C, that is identical with the recently prepared 2-(diphenylmethyl)imidaz0le[~1. When product ( I ) is boiled for 2 h in tetrahydrofuran/water (2: I ) it affords 2-(hydroxy-dipheny
