Abstract

A series of 2-[mercapto(cyano)methylene]-1,2,3,4-tetrahydroquinazolin-4-ones and 2-amino-4-methylpyrazolo[1,5-a]quinazolin-5(4H)-one were prepared from 2-cyanomethylquinazolin-4(3H)-ones via α-bromo derivatives 4 and amide oxime 8, respectively. The new compounds have been characterized by elemental analyses and 1H-nmr, in some cases by ir and 13C-nmr investigations.
