Copper-catalyzed coupling reaction of 2-thioxo-4-quinazolinone and thieno[3,2-d]pyrimidin-4-one methane sulphonamide with aryl iodides: Preparation of potential COX-2 selective inhibitors

Thio-aryl methane sulfonamide derivatives of 4-quinazolinone and thieno[2,3-d]pyrimidin-4-one were synthesized using powdery copper/copper(I) iodide as catalyst; their structural elucidation is also reported. These derivatives were planned as sulfur bioisosteres of selective COX-2 inhibitor drugs. Copyright Taylor & Francis Group, LLC.
