N¢ -{[(2-cyano-3-ethyl-3-methyl-3, 4-dihydronaphthalen-1-yl)amino]carbonothionyl}benzamide (II) was synthesized by reaction of 1-amino-3-ethyl-3-methyl-3,4-dihydronaphthalene-2-carbonitrile (aminonitrile I) with benzoylisothiocyanate. Condensation of aminonitrile I with phenylchloroformate yielded carbamate III, which was converted into mono-and disubstituted ureas IV and V via reaction with ammonia and aniline, respectively. A series of 2-substituted condensed triazolobenzoquinazolines (VI -XVI) was synthesized by condensation of carbamate III with hydrazides of aromatic and heteroaromatic carboxylic acids. The antineoplastic and antimonoamineoxidase properties of the synthesized compounds have been studied.
