(2‐Pyridylmethyl)( tert ‐butyldimethylsilyl)amine ( 1 ) can be lithiated once or twice yielding lithium (2‐pyridylmethyl)( tert ‐butyldimethylsilyl)amide ( 2 ) and dilithium (2‐pyridylmethanidyl)( tert ‐butyldimethylsilyl)amide ( 3 ), respectively. The oxidation of 3 with white phosphorus yields dilithium 1,2‐dipyridyl‐1,2‐bis(tert‐butyldimethylsilylamido)ethane ( 4 ) which crystallizes after partial hydrolysis as an adduct of the form 2 · 4 .
