(R)-N-[2-(N,N-Dimethylamino)ethyl]-N-methyl-1-[(S)-1 can be prepared in two steps from commercially available (-)-(R)-N,N-dimethyl-1-[(S)- 1′,2-bis(diphenylphosphino)ferrocenyl]ethylamine.

Although air stable at rt, storage under anhydrous conditions under an  inert atmosphere is recommended both to prevent the slow air oxidation of the phosphorus(III) ligating groups  and absorption of atmospheric moisture.
