反応手順
11.5 g of 5,6-dichloro-1-ethyl-2-methylbenzoimidazole and 20.6 g of N-(2-bromoethyl)succinimide were put into a 200-ml three-necked flask equipped with a stirrer and a reflux condenser and heated for 2 hours on an oil bath which has been heated to a temperature of 130° C. 10 ml of anisole was added to the mixture. The admixture was then allowed to stand for cooling. 50 ml of ethyl acetate was added to the admixture. The admixture was then refluxed for 30 minutes. After being allowed to cool to room temperature, the resulting crystal was filtered off, washed with acetone, and then dried at a temperature of 50° C. for 5 hours. Yield: 18.7 g (86%).
