Conditions

Temperature: 20 °C

Procedure

To a 10 percent w/v ethylbenzene solution of 135 g of 1-(2-hydroxyethyl)-2-isostearyl-3-benzylimidazolinium chloride at 20° C. is added 1.1 molar equivalents (24.5 g) of pyridine followed by dropwise addition of 1.3 molar equivalents (38.3 g) of methacryloyl chloride. The solution is stirred for 4 hours at 20° C. followed by separation of the supernatant liquid and the ethylbenzene removed to give an oil of 1-(2-methacryloxyethyl)-2-isostearyl-3-benzylimidazolinium chloride.
