Procedure

5 g of phenylalanine was added to 20 mL of butyric anhydride and the resulting mixture heated to about 100° C. for about 3 h. Excess butyric anhydride was then removed under reduced pressure to provide a solid residue that was recrystallized from ethanol to provide phenylalanine butyramide.
