Abstract

A novel 2-(methylthio)benzo[g][1,2,4]triazolo[1,5-a]quinazolin-5(4H)-one was synthesized employing dimethyl N-cyanoimidodithiocarbonate and 3-hydrazinyl-2-naphthoic acid as building blocks. Chemical transformation of the inherent lactam group in the target molecule provided access to a variety of heterocylic derivatives. The obtained compounds are characterized and confirmed by NMR, IR, and HREI-MS analyses.

Keywords: 3-hydrazinyl-2-naphthoic acid, cyclocondensation, dimethyl N-cyanoimidodithiocarbonate.
