A solution obtained by dissolving 0.6 g (2.3 mmol) of silver trifluoromethanesulfonate in 62 mL of methanol in a dark place was put in a dropping funnel attached to the 200-mL three-neck flask in a dark place. This methanol solution of silver trifluoromethanesulfonate was added dropwise into the reaction solution, and stirring was performed at room temperature for 26 hours. After reaction for the predetermined time, the reaction solution was filtered through Celite and the solvent of the resulting filtrate was distilled off to give an ocher solid. Then, all of the obtained ocher solid, 0.94 g (3.1 mmol) of 1-(2,6-diisopropylphenyl)-2-phenyl-1H-imidazole (abbreviation: HiPrpim), 15 mL of methanol, and 15 mL of ethanol were put in a 200-mL three-neck flask, and the mixture was refluxed for 36 hours. After reaction for the predetermined time, the solvent of the reaction solution was distilled off to give a yellow solid. A solution obtained by dissolving this yellow solid in tetrahydrofuran (THF) was filtered through a filter aid in which Celite, neutral silica, and Celite were stacked in this order, so that a yellow solution was obtained. The solvent in this yellow solution was distilled off to give a yellow solid. This yellow solid was purified by silica gel column chromatography. Toluene was used as a developing solvent. The solvent of the resulting fraction was distilled off, so that a yellow oily substance was obtained. This yellow oily substance was recrystallized with ethyl acetate and hexane to give a yellow solid.
