  • Patent number: 7301044
    Abstract: A process and intermediates for producing 3-amino nitrites. The process involves resolving an enantiomeric mixture of chiral 3-amino nitrites in the presence of a chiral acid in a solvent system to produce a chiral 3-amino nitrile salt. The process may further comprise a recrystalizing step, wherein an enantiomerically enriched 3-amino nitrile salt is produced. The process may further comprise a salt exchanging step, wherein another acid is added to the chiral 3-amino nitrile salt or the enantiomerically enriched 3-amino nitrile salt to produce another 3-amino nitrile salt.
