Synthesis of Nitro Derivative of 3-( 4--Chlorophenyl)-2-Methyl-Quinazolin-4- 0ne using Various Nitration Agents (article on The 2nd International Conference of the Indonesian Chemical Society October, 22-23 2013)
" ABSTRACT
Nitration of 3-(4-cblorophenyl)-2-metbyl-quinazolin-4-oneusing various nitration agents have been performed. The purpose of the experiment wa,;toget the best nitl'lltion agentsforthe synthesis of nitro derivative ofthe compomtd. The various nitration agentsused were:fuming nitric acid-concentrated sulfuric acid, silver nitrate-N-bromosuccinimide (NBS). eerie ammoniwn nitrate-silica supported sulfuric acid, and eerie ammonium ni􀃝ncentrated sulfuric acid. The results showed that nitrationwithfumingnitricacickoncentrated sulfuricacid obtained 3-( 4'-chloro-3 '-nitropheny l}-2- methyl-6-nitro--quinazolin-4-onein49. 74%yield. Thestructurewas confirmedusing FT-IRand1H-NMR The other nitration methods were not give the desired results. ... "
