Versuchsvorschrift
163 g (1.58 mol) 2-aminobutanoic acid are dissolved in acetic acid, and 242 g (2.37 mol) acetic anhydride are added dropwise. The mixture is stirred for 2 h at 100° C. until completion of reaction, then the solution evaporated to dryness in vacuo. The solid residue is suspended in ethyl acetate, filtered and washed with diethyl ether.
