Tow novels N-(2-aminophenyl)-2-quinazolinone-acetamide hydrochloride were synthesized through nucleophilic substitution,hydrogenation and acidification.The nucleophilic substitution was reacted between 2-bromo-N-(2-nitrophenyl)acetamide and various substituted quinazolinone under the catalysis of NaH.Among them,2-bromo-N-(2-nitrophenyl)acetamide was synthesized by a reaction between acetyl chloride and o-nitroaniline.And the substituted quinazolinone was synthesized by using aminobenzoic acid and formamide.The new process is characterized by short synthetic route,high yield and cheap raw materials.The structures of these compounds were confirmed by 1H NMR,IR spectra and HRMS.
