valuable chemicals at atmospheric pressure is an attractive topic. A novel method of preparing quinazoline derivatives by capturing CX2 (O, S) in reusable, room-temperature, reversible ionic liquids (ReILs) with high yields (up to 98%) at 40 °C and atmospheric pressure was developed in this paper. The different reaction conditions were optimized and the products were easily separated from the ReILs which

substituted-quinazolines showed significant antimycobacterial activity with the variations at position 2 and 4 offering additional antibacterialactivity against the different strains. Compared to previously reported 2,4-diaminosubstituted quinazolines, the bioisosteric replacement of the 2-amino with sulfur offered a successful approach to keep the high antibacterial potency while substantially improving safety profile
