Reaction Conditions

Reaction Steps

Five grams of ethyl 2-acetamido-3-aminobutyrate were dispersed in 10 ml of cold methanol, after which 1.51 g of potassium hydroxide in 15 ml of methanol were added. The mixture was stirred in an ice bath and then allowed to warm to 23° C. over a period of 18 hours. The solvent was removed at reduced pressure, and the residue was dissolved in a minimum of warm water and adjusted to a pH of 6.5 with hydrochloric acid. Upon cooling, crystals of 2-acetamido-3-aminobutyric acid were formed in a 95% yield.
