Synthesis of N-phenethylquinazolin-4-amines via silylation-amination mediated by hexamethyldisilazane
Abstract
N-phenethylquinazolin-4-amines have emerged as potential Mycobacterium tuberculosis cytochrome bd oxidase inhibitors and attractive scaffolds in tuberculosis drug discovery programs. The classical two-step strategy of chlorination-amination to synthesize such structures presents several operational issues accompanied by variable results. This work reports an efficient one-pot protocol to access N-phenethylquinazolin-4-amines via silylation-amination mediated by hexamethyldisilazane. The products were obtained with excellent yields (84–99%) under one-pot solvent-free conditions.
