摘要：
An acid-catalysed conversion of N-arylcarboxy-4-quinazolinones into 2-(2-aminoaryl)-4(1H)-quinazolinones has been observed. This reaction allows for a nucleophilic aromatic substitution reaction between aminobenzoic acids and 4-chloroquinazolines to form N-arylcarboxy-4-quinazolinones to be followed in situ by a conversion into 2-(2-aminoaryl)-4(1H)-quinazolinones in a one-pot tandem process.
