<p>Preparation of an amino-hydroxy-propionamide compound (I) comprises reacting an epoxy carboxylic acid amide compound (II) with an ammonia or an amine compound (III). JP2007332309AJP2007332309APreparation of an amino-hydroxy-propionamide compound of formula (I) comprises reacting an epoxy carboxylic acid amide compound of formula (II) with an ammonia or an amine compound (III) of formula (R 2>NH(R 3>)). Either R 1>-R 5>(1-8C)-alkyl, HO-(1-8C)-alkyl, (2-8C)-alkoxyalkyl, (6-18C)-aryl, (7-19C)-aralkyl, (3-18C)-heteroaryl, (4-19C)-heteroaralkyl, (1-8C)-alkyl-(6-18C)-aryl, (1-8C)-alkyl-(3-18C)-heteroaryl, (3-8C)-cycloalkyl, (1-8C)-alkyl-(3-8C)-cycloalkyl or (3-8C)-cycloalkyl-(1-8C)-alkyl; or R 4>R 5>, R 2>R 3>(2-8C)-alkylene bond. Provided that if R 4> and/or R 5> is H, then R 1>-R 4> is H and R 1> is not phenyl. Independent claims are included for: (1) an enantiomerically enriched 3-alkyl-oxirane carboxylic acid-N-cyclopropylamide compound of formula (IV) (where R is a linear (1-8C)-alkyl-residue); and (2) a salt of amino-hydroxy-cyclopropylamide compound of formula (V) with chiral acids.
