Procedure

2-Chlorocycloheptimidazole (0.78 g) was added to 4 ml of anisole, 0.93 g of methyl trifluoromethanesulfonate was added dropwise thereto, and the mixture was stirred at room temperature for 40 minutes. Then, 50 ml of ethyl acetate was added to the reaction solution, and deposited crystals were collected by filtration and dried.
