Sodium salicylate (1.64 g, 10 mmole) was dissolved in DI water (10 mL), and the sodium salicylate solution was added to a solution of N,N-dimethyl-N-(ethylcarbonylmethyl)-N-[2-(methacryloyloxy)ethyl]ammonium bromide (3.24 g, 10 mmole) in DI water (10 mL). The reaction was stirred at 25° C. for 24 hours. The product was extracted by chloroform and dried in vacuum and analyzed. 1H NMR (300 MHz, D2O): δ 7.0-7.67 (m, 1H), 7.35-7.28 (m, 1H), 6.86-6.79 (m, 2H), 6.11 (s, 1H), 5.65 (s, 1H), 5.03 (s, 2H), 4.66 (t, 2H, J=3.0 Hz), 4.42 (t, 2H, J=3.0 Hz), 4.20 (q, 2H, J=7.2 Hz), 3.76 (s, 6H), 1.92 (s, 3H), 1.29 (t, 3H, J=6.0 Hz).
