(±)-2-Methyl-2-propanesulfinamide is used in the synthesis of 4-sulfonyliminopiperidine and its reaction with benzyl Grignard to form an important pharmaceutical building block, 4-benzyl-4-aminopiperidne. It is also used to prepare spiro tosylaziridines via methylene insertion into the derived sulfonylimine.
