The present invention discloses a method for preparing 3-amino-N-cyclopropyl-2-hydroxyl-hexanamide. The invention relates to the technical field of the preparation of pharmaceutical intermediates. The method uses trans-2-hexenoic acid as the starting material, through the steps of epoxidation, ring-opening by nitrile, amidation, etc., to obtain the final product 3-amino-N-cyclopropyl-2-hydroxyl-hexanamide. The method uses easily-obtainable materials, requires mild reactive conditions, and adopts stable processes. Therefore it is suitable for large scale industrial production.

Cyanohydrins (α-hydroxy nitriles) are a special type of nitriles that readily decompose into hydrogen cyanide (HCN) and the corresponding carbonyl compounds. Hydration of cyanohydrins that are readily available through cyanation of aldehydes and ketones provides the most straightforward route to valuable α-hydroxyamides. However, due to low stability of cyanohydrins and deactivation of the catalysts
