    "protocol": "In a three-neck round-bottom flask, add 6.0 g of Na2B4O7·10H2O and 3.0 g of Na2CO3 to 250.0 mL of deionized water. Stir and degas the solution with high purity argon (99.999%) for 2 hours. Under an argon atmosphere, add 1.5 g of dopamine hydrochloride to the solution and stir for an additional 30 minutes. Drop-wise add 3.0 mL of acryloyl chloride to the flask at 0 °C, then add 4.5 g of Na2CO3 to maintain the pH above 9 during the reaction. Stir the mixture for 12 hours at room temperature. Adjust the pH to 1-2 using a 6 mol/L HCl solution. Extract the solution with ethyl acetate, wash the organic layer with a 0.1 mol/L diluted HCl solution, and dry over MgSO4. Remove the solvent in vacuum to obtain the crude product, which is then purified by flash silica gel column chromatography using ethyl acetate and petroleum ether, yielding a white solid with an 80% yield."
