In a 40-mL scintillation vial, 12.0 g (0.05 moles) of lauryl acrylate are charged followed by the slow addition of 5.0 g (0.05 moles) of 1-methyl piperazine. The mixture is agitated using a magnetic stirrer bar and heated to 85° C. for at least 16 hours using a heating block. The final product is a light brown liquid at ambient temperature. Complete conversion is apparent from the lack of olefin protons in the 1H-NMR spectra. 1H-NMR (300 MHz, CDCl3): δ 3.83 (t, 6.6 Hz, 2H), 2.45 (t, 7.3 Hz, 2H), 2.24 (m, 10H), 2.02 (s, 3H), 1.38 (t, 6.8 Hz, 2H), 1.03 (m, 18H), 0.65 (t, 7.1 Hz, 3H). 13C-NMR (75 MHz, CDCl3): δ 171.78, 63.92, 54.64, 53.12, 52.39, 45.53, 31.93, 31.45, 29.19, 21.17, 29.12, 29.08, 28.89, 28.80, 28.20, 25.47, 22.20, 13.63.
