Process for preparing 2(1H)-quinazolinone derivatives

2(1H)-Quinazolinone and quinazolinethione derivatives having excellent pharmacological activities are produced in high yield with high purity by heating the corresponding 3,4-dihydro-2(1H)-quinazolinone or quinazolinethione derivatives together with sulfur in an inert solvent.

Production of quinazolinone compounds

2(1H)-Quinazolinone derivatives, which are useful as anti-inflammatory agents, are prepared by heating or hydrolyzing an acylurea derivative. The acylurea derivative can be prepared by either reacting an indole derivative with an oxidizing agent or reacti

Process for preparing quinazolines

Quinazoline derivatives which have anti-inflammatory, antiviral, uricosuric activities are prepared by reacting an indole-2-carbonylazide derivative with an oxidizing agent under mild conditions.
