title: Synthesis of 4-(5-iodo-3-methylpyrazolyl) phenylsulfonamide and its elaboration to a COX II inhibitor library by solution-phase suzuki coupling using Pd/C as a solid-supported catalyst.
abstract: An effective synthesis of 4-(5-iodo-3-methylpyrazolyl) phenylsulfonamide has been developed. This aromatic iodide template served as an efficient oxidative addition partner for the preparation of a solution-phase library of Celecoxib analogues via Suzuki coupling using Pd/C, a readily filterable catalyst.
