This is a crazy idea that might not work. When looking at the methods for creating LiAlH4 I decided that I didn't like them much at all.
An idea hit me. In the redction of MDP2NP to MDA could a person just add Li and amalgamated aluminum to perform the redction and not have to go through the trouble to synthesizing LAH?
It does not work like that. LiAlH
4 can only be made from LiH and etheral AlCl
3 outside of an industrial setting.
