Synthesis of Acryloyl β-alanine-Acryloyl β-alanine (ABA) was prepared following a modification of a procedure preported earlier. Typically, β-alanine and NaOH aqueous solution (30 mL, and the solution was cooled down to 0 o C in an ice bath. Acryloyl chloride was added to the aqueous solution of β-alanine dropwise under nitrogen atmosphere at 0-5 o C. After mixing, the reaction mixture was stirred continuously for 3 h at 0 o C. After the reaction, the reaction mixture was added with conc HCl (37 %) and adjusted pH (2). The unreacted chemicals and byproducts were removed by extraction with ethyl acetate.
