Reaction Steps

In a 100 ml flask equipped with a stirrer, a condenser and a calcium chloride dryer tube were charged 3.7 g of 1-methylimidazole and 10.0 g of octadecyl p-toluenesulfonate, and the mixture was stirred at 120° C. for 5 hours. After cooling the reaction mixture to room temperature, precipitated crystals were collected by filtration under reduced pressure. The resulting crystals were recrystallized from acetone to obtain 10.9 g of the title compound. Melting point: 71° C.
