Abstract
This paper describes the preparation of some pyrazolo[1,5-a]-, 1,2,4-triazo lo[1,5-a]- and imidazo[1,2-a]pyrimidines substituted on the pyrimidine moie ty by a 4-[(N-acetyl-N-ethyl)amino]phenyl group. A new synthesis of related benzo[h]pyrazolo[1,5-a]-, benzo[h]pyrazolo[5,1-b]- and benzo[h]1,2,4-triaz olo[1,5-a]quinazolines is also reported.
