7-BROMO-1H-QUINAZOLIN-4-ONE Chemical Properties,Uses,Production

Application

7-Bromo-3,4-dihydroquinazolin-4-one is a quinazolone compound. Quinazolones are a class of nitrogen-containing heterocyclic compounds with good biomedical activity, due to their broad range of biological and pharmaceutical activities.

Synthesis

2-Amino-4-bromobenzoic acid

20776-50-5

formamide

77287-34-4

7-BROMO-1H-QUINAZOLIN-4-ONE

194851-16-6

General procedure for the synthesis of 7-bromo-3,4-dihydroquinazolin-4-one from 2-amino-4-bromobenzoic acid and compound (CAS: 77287-34-4): 0.0 g (1.56 mol) of 2-amino-4-bromobenzoic acid was suspended in 970 mL of formamide, followed by stirring of the reaction for 12 hours at 170°C. Upon completion of the reaction, a conventional post-processing was carried out to give 326.0 g of 7-bromo-3H-quinazolin-4-one; which was analyzed by HPLC/MS as a solid product with (M + H)+ = 226.
