Reaction Steps
To a stirring mixture of 2-aminoisobutyric acid (52.08 g, 0.51 mol), sodium hydroxide (20.20 g, 0.51 mol), 200 mL water, and 50 mL chloroform cooled to −12° C., was added a solution of 2-bromopropionyl bromide (100 g, 0.46 mol) in 150 mL chloroform over 15 minutes. The temperature was maintained between −15 and −12° C. during the addition. The reaction mixture was then allowed to warm to room temperature and the precipitated solid was filtered. The solid was mixed with 700 mL hot toluene, and then cooled. The white solid was then filtered and dried under vacuum. A yield of 77.60 g (70%) was obtained.
