実験手順
1.41 parts of N-acetoacetyl-L-aspartic acid were dissolved in 25 parts by volume of acetic acid, and 5 parts by volume of acetic anhydride were added and the mixture was stirred overnight under nitrogen. Solvent was removed under vacuum at 40°-45° C. 50 parts by volume of acetic acid were added and the evaporation repeated to form N-acetoacetyl-L-aspartic anhydride.
