SYNTHESIS AND CHARACTERIZATION OF 2METHYL 3-AMINO QUINQZOLIN-4(3H) ONE

About author : Ramesh Dhani Dept. of  Pharmaceutical Chemistry JNTUA-OTRI, Anantapur,India ABSTRACT: Quinazoline is a bicyclic compound earlier known as benzo-1, 3-diazine. The name quinazolinone (German: Chinazolin) was proposed for its compound by wedding, on observing that this was isomeric with the then compound crinoline and quinaoxaline. The numbering of the quinazoline ring system which is currently used was suggested ... Read More »
