99% To a suspension of 0.045 mol (+)-(R)-2-(4-chloro-2-methylphenoxy) propionic acid in 40 mL of distilled water was added 10%> aqueous solution of KOH dropwise. The mixture was heated to a temperature of 313K. A stoichiometric amount of <strong>[538-71-6]domiphen bromide</strong> was added to the resultant clear solution and the reaction mixture was stirred for 24 hours. A two-layer mixture formed as a result of reaction and the product precipitated in the form of the lower layer. Chloroform (40 mL) was added and the layers were separated. The organic phase was washed with deionized water until the bromide ions were no longer present. The chloroform was evaporated and the residue dried at 353K under vacuum.

> 92% With potassium hydroxide; In water; at 59.84℃; for 12h; The API-IL domiphen L-proline ([DOM][L-PRO]) was prepared from <strong>[538-71-6]domiphen bromide</strong>and L-proline. General procedure is according to the procedures described in the literature[9]. 0.05 mol <strong>[538-71-6]domiphen bromide</strong> was dissolved in 40 mL distilled water. After thesolution was clear, equimolar amount of L-proline and potassium hydroxide in distilledwater (50 mL) were added. The mixture was stirred at 333 K for 12 h. Dichloromethanewas added and the mixture was allowed to stand overnight at room temperature. Thecrystalline KCl was removed by filtration and dichloromethane by distillation. Additionof dichloromethane was repeated until no further precipitation of KCl could be detected.The residue was dried overnight in vacuum at 80 C. The product was obtained as awhite solid with yield over 92%. The water content of the API-IL was determined byKarl-Fischer measurement, and the value was about 350 ppm. For additional characterization,the IR and 1H-NMR spectra of [DOM][L-PRO] were recorded (Figs. S1 andS2 in supplementary material). FT-IR spectra were recorded as KBr pellets, in the4000-500 cm-1 range on a Nicolet IR-470 spectrophotometer (Perkin Elmer). 1H NMRspectra were recorded in CDCl3 solution at 298 ± 1 K using Bruker DPX at 400 MHzand the solvent peak was used as reference. Elemental analysis was performed on aThermo Flash EA 1112 elemental analyzer.The characterization values obtained were: IR(KBr, cm-1): 3416(s), 3060(m), 3009(m),1597(s), 1591(s), 1497(s), 1467(m), 1410(m), 1231(s), 1176(m), 1032(m), 754(s), 720(w),690(s); 1H NMR: (400 MHz, CDCl3) d 7.32(m, 2H), 7.03(t, J = 12 Hz, 1H), 6.89(d,J = 8 Hz, 2H), 4.49(d, J = 4 Hz, 2H), 4.29(m, 2H), 3.71(q, 5H), 3.61(m, 2H), 3.48(s, 6H),1.24(m, 23H), 0.87(t, J = 12 Hz, 3H); elemental analysis found (%): C 72.25, H 10.87, N6.20; calc. for C27H48N2O3 (448.85):C 72.29, H 10.78, N 6.24.
