Procedure

Methyl 3-(4-methylpiperazin-1-yl)propanoate 40.0 g (0.21 moles) and dodecylamine 39.7 g (0.21 moles) are charged into a 3-neck 250-mL round bottom flask equipped with a Dean-Stark trap, thermocouple, and reflux condenser. The mixture is agitated using a magnetic stirring bar and heated to 185° C. for five hours. The volume of methanol that is distilled from the reaction is used to monitor the progress of the reaction. Evidence of the chemical transformation is observed by thin layer chromatography (TLC) analysis using a 4:1 CHCl3/MeOH as mobile phase. The final product is a light yellow solid at ambient temperature. 1H-NMR (300 MHz, CDCl3): δ 2.98 (m, 2H), 2.07 (m, 1511), 1.27 (m, 2H), 1.0 (m, 18H), 0.65 (t, 6.7 Hz, 3H). 13C-NMR (75 MHz, CDCl3): δ 171.70, 54.60, 54.39, 54.34, 53.45, 51.86, 45.39, 38.45, 31.60, 31.38, 29.14, 29.11, 28.93, 28.85, 28.83, 26.65, 22.15, 13.61.
