suzuki reaction | [Purification Methods]
Distil or recrystallise the diamine from pet ether under N2 or Ar. Store it as above. The 1S,2S-base D-tartrate salt has M 264.3, m 180 -1 8 4o(dec) and [] 25 -12.5o (c 4, H2O) from which the free base can be purified or optically enriched. It is a useful chiral synthon. [Fjii et al.
