preparation example Construction
[0141] The preparation process of the following examples 1 to 16 is carried out in two steps, and the reaction scheme is as follows:
[0142] A+B→Intermediate I
[0143] Intermediate I+D→E.
[0144] The structural formulas of reactants A, B, intermediate I, reactant D and product E in the examples are shown in Tables 1 and 2, respectively.

[0153] The specific reaction conditions for each example are as follows.
Embodiment 1
[0155] Add 1.35g (15mmol) of N,N-dimethylethanolamine (DMEA, compound A) and 4.35g (22.5mmol) of bromooctane (compound B) into a round bottom flask, and place it in an oil bath at 45°C React in medium for 2 hours, measure 12 mL of acetone as a solvent and add it to a round-bottomed flask, and then reflux for 12 hours; after the reaction, dry the solvent under reduced pressure at 60°C to obtain a white solid, which is washed several times with anhydrous petroleum ether, and placed in a vacuum oven Dry to obtain intermediate I, which is stored in a bottle for later use. The yield of this intermediate is 92%, and the nuclear magnetic resonance data is: 1H NMR (600MHz, D 2 O)δ3.92(tt, J=4.9,2.2Hz,2H),3.41–3.33(m,2H),3.29–3.22(m,2H),3.01(s,6H),1.66(ddd,J=15.0 ,9.4,5.6Hz,2H), 1.32–1.10(m,10H),0.75(t,J=6.8Hz,3H).
[0156] Take intermediate I, 1.42g (5mmol) and sodium carbonate 0.8g are dissolved in 10mL deionized water to configure a solution and add it to the dropping funnel for us...
Embodiment 2
[0158] Add 1.35g (15mmol) of N,N-dimethylethanolamine (DMEA, compound A) and 9.13g (22.5mmol) of compound B (bromooctadecane) into a round bottom flask, and place in an oil bath at 35°C React in the pot for 5 hours, measure 20 mL of ethanol as a solvent and add it to the round bottom flask, and then reflux for 8 hours; after the reaction, spin the solvent under reduced pressure at 40 ° C to obtain a white solid, wash it with anhydrous ether several times, and put it in a vacuum oven Oven dry, obtain intermediate (quaternary ammonium salt alcohol, i.e. intermediate I) and preserve in the bottle for use, the productive rate of this intermediate is 92%, and nuclear magnetic resonance data is: 1 H NMR (600MHz,D 2 O)δ3.92(tt, J=4.9,2.2Hz,2H),3.41–3.33(m,2H),3.29–3.22(m,2H),3.01(s,6H),1.66(ddd,J=15.0 ,9.4,5.6Hz,2H), 1.32–1.10(m,30H),0.75(t,J=6.8Hz,3H).
[0159] Take 4.22g (10mmol) of the intermediate (quaternary ammonium salt alcohol) and 1.3g (10mmol) of N,N-diisopropylethylamine...
