title: Efficient palladium-catalyzed synthesis of 3-aryl-4-indolylmaleimides.
abstract: Improved palladium catalysts for the Suzuki coupling of 3-bromo-1-methyl-4-(2-methyl-3-indolyl)maleimide have been developed. The coupling of both aryl- and heteroarylboronic acids proceeds smoothly in good to excellent yields at low catalyst loading.
