2], antiproliferative , antigiogenic , antiarrhythmic and analgesic  activities and antihypertensive properties , while quinazolines exhibit antitumor , antimicrobial  antitubercular , antiagonists , anticonvulsant  and analgesic activities.
Refluxing of compound 1 and thiourea in absolute ethanol with a catalytic amount of potassium hydroxide furnished quinazoline thione derivative 9 in a good yield.
Chemically the members of the genus Sida contain [beta]-phenethylamines ([beta]-phenethylamine, ephedrine and [phi] ephedrine), quinazolines
(vasicine, vasicinol and vasicinone) and carboxylated tryptamines in addition to choline and betaine .
The book contains six chapters covering synthesis, reactions and applications in the following subject areas: pyridazines, cinnolines, benzocinnolines and phthalazines; pyrimidines and quinazolines
; pyrazines and related ring structures; phenzine, oxazine, thiazine and sulphur dyes; quinazoline
alkaloids; six-membered rings with three or more hetero-atoms.

We now wish to report herein a short MW assisted synthesis of hexahydroquinazolin-5(6H)-ones and bis-hexahydroquinazolin-5(6H)-ones bearing methyl group in position 1 of quinazoline
Cinnoline, quinoxaline, and pthalazine (Figure-1) are the structural isomers of quinazoline
