反応手順
A solution of 5.16 g (0.024 mol) of 1-bromo-2-(3-methylphenyl)-2-oxoethane and 2.15 g (0.026 mol) of 1-methylimidazole in approximately 30 ml of diethyl ether was stirred at room temperature for about 19 hours. The reaction solvent was decanted and the resulting brown residue was washed with diethyl ether. The residue was washed with not acetonitrile and recrystallized twice from acetonitrile/diethyl ether to afford 1.74 g of 1-methyl-3-[2-(3-methylphenyl)-2-oxoethyl]-1H-imidazolium bromide as white needles. (25% yield) mp=185°-187° C.
